Class E IP Address Space Helps GKE Manage IPv4 Depletion

Using Class E IPv4 Address space to help GKE address IPv4 depletion problems. The need for private IPv4 addresses is growing along with the amount of services and apps hosted on Google Kubernetes Engine (GKE) (RFC 1918). The RFC1918 address space is becoming harder to come by for a lot of big businesses, which makes IP address depletion a problem that affects their application scalability.

This precise address depletion problem is resolved by IPv6, which offers a large number of addresses. But not every business or application is prepared for IPv6 just yet. You may continue to expand your company by entering the IPv4 address space (240.0.0.0/4), which can handle these problems.

Class E addresses (240.0.0.0/4) are set aside for future usage, as indicated in RFC 5735 and RFC 1112, as stated in Google VPC network acceptable IPv4 ranges; nevertheless, this does not preclude you from using them in certain situations today. Google will also provide tips for organizing and using GKE clusters with Class E.

Recognizing Class E addresses

IPv4 addresses

Some typical criticisms or misunderstandings about the use of Class E addresses are as follows:

Other Google services do not function with class E addresses. This is untrue. Class E addresses are included in the acceptable address ranges for IPV4 that Google Cloud VPC offers. Furthermore, private connection techniques using Class E addresses provide access to a large number of Google controlled services.

Communicating with services outside of Google (internet/on-premises/other clouds) is limited when using Class E addresses. False. You may use NAT or IP masquerading to convert Class E addresses to public or private IPv4 addresses in order to access destinations outside of Google Cloud, since Class E addresses are not routable and are not published over the internet or outside of Google Cloud. Furthermore,

a. Nowadays, a large number of operating systems support Class E addresses, with Microsoft Windows being the prominent exception.

b. Routing the addresses for usage in private DCs is supported by several on-premises suppliers (Cisco, Juniper, Arista).

There are scale and performance restrictions on Class E addresses. This is untrue. Regarding performance, there is no difference between the addresses and other address ranges used by Google Cloud. Agents can grow to accommodate a high number of connections without sacrificing speed, even with NAT/IP Masquerade.

Therefore, you may utilize Class E addresses for private usage inside Google Cloud VPCs, for both Compute Engine instances and Kubernetes pods/services in GKE, even though they are reserved for future use, not routable over the internet, and shouldn’t be publicized over the public internet.

Advantages

Class E IP Addresses

Despite these limitations, Class E addresses provide some benefits:

Large address space: Compared to standard RFC 1918 private addresses (around 17.9 million addresses vs. about 268.4 million addresses for it), Class E addresses provide a much bigger pool of IP addresses. Organizations experiencing IP address depletion will benefit from this abundance as it will enable them to expand their services and applications without being constrained by a finite amount of address space.

Growth and scalability: It addressing’s wide reach facilitates the simple scalability of services and apps on Google Cloud and GKE. IP address restrictions do not prevent you from deploying and growing your infrastructure, which promotes innovation and development even during times of high consumption.

Effective resource utilization: By using Class E addresses to enhance your IP address allocation procedures, you may reduce the possibility of address conflicts and contribute to the efficient use of IP resources. This results in reduced expenses and more efficient operations.

Future-proofing: Although it is not supported by all operating systems, its use is anticipated to rise in response to the growing need for IP addresses. You can future-proof your infrastructure scalability to enable company development for many years to come by adopting Class E early on.

Class E IP addresses

Things to be mindful of

Even though Class E IP addresses provide many advantages, there are a few crucial things to remember:

Compatibility with operating systems: At the moment, not all operating systems enable Class E addressing. Make sure your selected operating system and tools are compatible before putting Class E into practice.

Software and hardware for networking: Check to see whether your firewalls and routers (or any other third-party virtual appliance solutions running on Google Compute Engine) are capable of handling the addresses. Make sure any programs or software that use IP addresses are updated to support it as well.

Migration and transition: To ensure there are no interruptions while switching from RFC 1918 private addresses to it, meticulous preparation and execution are needed.

How Snap implemented Class E

Network IP management is becoming more difficult due to the growing use of microservices and containerization systems such as GKE, particularly by major clients like Snap. Snap’s finite supply of RFC1918 private IPv4 addresses was rapidly depleted with hundreds of thousands of pods deployed, impeding cluster scalability and necessitating a large amount of human work to release addresses.

Originally contemplating an IPv6 migration, Snap ultimately opted to deploy dual-stack GKE nodes and GKE pods (IPv6 + Class E IPv4) due to concerns over application readiness and compatibility. In addition to preventing IP fatigue, this approach gave Snap the scale of IP addresses it required for many years to accommodate future expansion and cut down on overhead. Furthermore, this technique was in line with Snap’s long-term plan to switch to IPv6.

Fresh clusters

Requirement

Construct native VPC clusters.

Steps

Make a subnetwork with supplementary ranges for services and pods, if desired. It range (240.0.0.0/4) has CIDRs that may be used in the secondary ranges.

When creating the cluster for the pod and services CIDR ranges, use the previously generated secondary ranges. This is an example of the user-managed secondary range assignment mechanism.

Setup IP masquerading to source network address translation (SNAT) to map the IP address of the underlying node to the source network address.

Migrating clusters

Requirement

The clusters need to be native to the VPC.

Steps

It is not possible to modify the cluster’s default pod IPv4 range. For more recent node pools that support Class E ranges, you may add pod ranges.

Workloads from earlier node pools may potentially be moved to newer node pools.

IPv4 Vs IPv6

Making the switch from IPv4 to IPv6 Class E

For enterprises experiencing IP depletion, switching to dual-stack clusters with the IPv4 and IPv6 addresses now is a wise strategic step. By increasing the pool of IP addresses that are accessible, it offers instant relief and permits expansion and scalability inside Google Cloud and GKE. Furthermore, implementing dual-stack clusters is an essential first step toward a more seamless IPv6-only transition.

What are IP addresses and DNS? Figure them out and the internet will never get stuck again!

Today we are going to talk about a basic issue that many people encounter: IP address and DNS. although these two terms are often heard in our daily surfing, but many people may not be clear about their specific meaning and role. Don't worry, you'll be able to figure out their differences and roles after reading this article!

IP address, simply put, is the “network identity card” of each device when we surf the Internet. Each device connected to the Internet will be assigned a unique IP address, just like our home has a specific postal address, all the letters are sent to your home through this address, the role of the IP address is to make the data packets accurately and correctly delivered to the target device.

There are two types of IP addresses:

·IPv4 address: it is the most common IP format and consists of four segments of numbers (e.g. 192.168.1.1). Each segment has a value between 0 and 255. IPv4 is able to provide about 4.3 billion addresses, which seems like a lot, but it is now running out.

·IPv6 addresses: IPv6 is a new generation of IP addresses, consisting of more numbers and letters (e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:7334), which theoretically can provide almost unlimited addresses, solving the problem of insufficient IPv4 addresses.

DNS is our “Internet phone book”. When you enter a web address (e.g. www.711proxy.com) into your browser, DNS works by converting the domain name into a corresponding IP address, because computers can only recognize the target website by its IP address.

How does DNS work?

As a simple example, when you want to visit a certain website, for example, you type in “www.example.com”, then your computer will send a request to the DNS server, asking “What is the corresponding IP address of this domain name?”. The DNS server will check and tell you “the IP address of this domain name is 123.45.67.89”, and then your computer will access the corresponding website through this IP address.

The relationship between IP address and DNS

IP address and DNS are like the navigation system and address book in the network world, IP address is responsible for telling the data how to find the right target device on the network, while DNS is to make us easy to use easy-to-remember domain name to access the website instead of memorizing those complicated numbers.

IP address and DNS are the foundation of our daily internet access, and understanding their roles will not only help you improve your internet efficiency, but also solve some common internet problems, such as web pages not opening, internet latency, and so on.

If you want to make your network faster and more stable, using 711Proxy's proxy IP service is a good choice! We provide global high-quality IP resources to help you easily cope with all kinds of network challenges~!

The Impact of PIA VPN on Cloudflare 1.1.1.1 DNS

Privacy is a top concern for internet users, and VPNs have become a popular tool for protecting online data. One well-known VPN provider is Private Internet Access (PIA), which offers a secure and private connection to the internet. When using a VPN like PIA, all internet traffic is encrypted and redirected through their servers, masking the user's IP address and location.

Many users also rely on Cloudflare's 1.1.1.1 DNS resolver service for faster and more private browsing. Cloudflare's DNS service promises faster browsing speeds and increased privacy compared to traditional DNS resolvers provided by internet service providers.

When using a VPN like PIA in conjunction with Cloudflare's 1.1.1.1 DNS resolver, users can experience enhanced security and privacy benefits. The VPN encrypts internet traffic, making it difficult for third parties to intercept or track user activities online. By rerouting DNS requests through Cloudflare's secure 1.1.1.1 resolver, users can further enhance their online privacy and protect against DNS hijacking and other malicious attacks.

However, using a VPN with a DNS resolver like 1.1.1.1 may lead to some trade-offs in terms of browsing speed. The additional encryption and rerouting of traffic through different servers can sometimes result in slower internet speeds. Users should weigh the benefits of enhanced privacy and security against potential decreases in browsing performance when deciding to combine PIA VPN with Cloudflare's 1.1.1.1 DNS resolver.

In conclusion, the combination of PIA VPN and Cloudflare's 1.1.1.1 DNS resolver can offer users a robust solution for enhancing their online privacy and security. By understanding the impact of these tools on their internet browsing experience, users can make informed decisions about their online security practices.

An article to see the key differences between IPv4 and IPv6!

It's time for me to share real stuff again ~ Today we are going to discuss the difference between IPv4 and IPv6. ipv4 and ipv6 are the two versions of the internet protocol, which are the basis of network communication. In this article, we will briefly explain the difference between them and hope to add a new understanding to your network knowledge.

What is IPv4?

IPv4, or Internet Protocol version 4, is the version of IP that is widely used today. It uses a 32-bit address space to provide approximately 4.3 billion unique IP addresses.IPv4 addresses are usually represented as four decimal numbers, each ranging from 0 to 255, separated by dots, e.g. 192.168.1.1.

What is IPv6?

IPv6, or Internet Protocol version 6, is the successor to IPv4 and solves the problem of IPv4 address exhaustion. It uses a 128-bit address space to provide approximately 3.4 x 10^38 unique IP addresses.IPv6 addresses are typically represented as eight sets of hexadecimal numbers, each consisting of four hexadecimal digits separated by a colon, for example 2001:0db8:85a3:0000:0000:8a2e:0370:7334.

Main differences between IPv4 and IPv6

1)Address space

1.IPv4: 32 bits, about 4.3 billion addresses.

2.IPv6: 128 bits, about 3.4×10^38 addresses.

2)Address representation

1.IPv4: dotted decimal, e.g. 192.168.1.1.

2.IPv6: colon in hexadecimal, e.g. 2001:0db8:85a3:0000:0000:8a2e:0370:7334.

3)Address Configuration

1.IPv4: manual configuration or DHCP allocation.

2.IPv6: supports auto-configuration (SLAAC) and DHCPv6.

4)Security

1.IPv4: relies on application layer protocols for security, such as IPsec.

2.IPv6: Built-in IPsec support.

5)Multicast and Broadcast

1.IPv4: Supports broadcast and multicast.

2.IPv6: does not support broadcast, only multicast and unicast.

I hope that through today's sharing, you have a clearer understanding of the difference between IPv4 and IPv6. With the development of the Internet, the popularization of IPv6 is a big trend.
