3_ Hostinger :

Hostinger is quickly establishing itself as one of the leaders of hosting websites.  It is a very large company, independently owned (not part of the eig brands, such as hostgator crocodile / bluehost) with multiple offices all over the world.  It hosts over 30,000,000 domain names!

 The company offers shared, business, and VPS-hosting currently only for Linux based.  It offers a variety of payment methods, including Bitcoin and other cryptocurrencies!

 Two key points about hostinger.  Positives:

 Performance: their speed, uptime, response times are one of the best in this class.  Part of this feature is due to the presence of 7 data centers located across 5 continents: North America (USA), Europe, UK, Brazil, and Asia.

 Custom control panel: Hostinger has a neat and extremely easy-to-use custom control panel built, which enables very fast development, feature releases and feedback loop with clients.

 Support: Hostinger's customer success department provides 24/7 support and is ready to answer all questions within seconds.  All agents are highly skilled and professional.  They have live chat assistance, which is available once you become their client, and log into their system.

 WordPress improvements: HTTP / 2, IPv6 enabled, PHP7, nginx caching, gzip compression, spam and threat detection.  This enables hostinger to serve up to 3 times more requests per second.

 Technological advantages:

 - HTTP / 2 support for nginx and dual Apache web server architecture

 - Dual cache (custom memcached + nginx cache)

 SSD raids for maximum I / O speeds

 - Daily backups

 The latest PHP 7+

 - HA network preparation

 - cloudlinux + lve container for each account

 Pricing: Hostinger is well known for always having low pricing, and special promotions.  It does offer a standard 30 day money-back guarantee.

 Payment methods: credit card (Visa, MasterCard, American Express, Discover, etc.);  Paypal cryptocurrencies are supported (Bitcoin, Ethereum and many other cryptocurrencies);  Other local payment methods are also supported in the local markets.

 A pair of important notes.  Negatives:

 The lowest package includes only 1 database and 1 email box only, not SSL (which is a must for any websites nowadays), which is why we don't include this plan in our list.

 Their second plan, currently on sale for $ 2.95 a month, also doesn't include free SSL, all of their lesser packages don't include daily backups.

 They do not have a price renewal guarantee like some of the other service providers listed in our directory, and their renewal price appears to be 3-4 times higher than their initial price!

 Also, the standard shared hosting packages are not developer friendly as they do not include support for python, ruby, postgeneral, nodejs.

Amazon Route 53 Resolver supports HTTPS DNS

As of right now, both incoming and outgoing Resolver endpoints can use the DNS over HTTPS (DoH) protocol with Amazon Route 53 Resolver. As the name implies, DoH allows data sent for Domain Name System (DNS) resolutions to be encrypted via HTTP or HTTP/2 over TLS.

By using TLS encryption to prevent eavesdropping and modification of DNS data during communication between a DoH client and the DoH-based DNS resolver, DoH improves security and privacy.

This aids in the implementation of a zero-trust architecture, in which all network traffic is encrypted and no actor, system, network, or service operating inside or outside of your security perimeter is trusted. Utilizing DoH also facilitates adherence to suggestions like those outlined in this US Office of Management and Budget (OMB) memo.

Support for DNS via HTTPS in Amazon Route 53 Resolver

In hybrid cloud setups, you can utilize Amazon Route 53 Resolver to resolve DNS queries. For instance, it permits DNS requests from any location inside your hybrid network to be accessed by AWS services. You can configure both inbound and outgoing Resolver endpoints to achieve this:

DNS queries from your on-premises network or another VPC can reach your VPC through inbound resolver endpoints.

DNS requests can be sent from your VPC to another VPC or your on-premises network using outbound resolver endpoints.

Following the configuration of the Resolver endpoints, you can create rules that indicate which domain names you wish to have forwarded (inbound) and outbound (from your VPC to an on-premises DNS resolver).

You may now choose the protocols to utilize when creating or updating an inbound or outbound Resolver endpoint:

DNS over port 53 (Do53), which transmits packets via TCP or UDP.

DNS over HTTPS (DoH), encrypts the data with TLS.

Both, depending on the DNS client’s preference.

There is a particular implementation (DoH-FIPS) for incoming endpoints in order to ensure FIPS compliance.

Let’s examine how this functions in real life

Using the Amazon Route 53 Resolver with DNS over HTTPS

You can select Inbound endpoints in the Route 53 console by going to the Resolver part of the navigation pane. You can select Create inbound endpoint there.

You can choose the security group, the VPC, the endpoint type (IPv4, IPv6, or dual-stack), and then enter the endpoint’s name. In the Protocols for this endpoint option, you can choose Do53, DoH, and DoH-FIPS to permit the use of both encrypted and unencrypted DNS resolutions.

Then set up the IP addresses for DNS queries after that. You can choose two Availability Zones and a subnet for each. You may use the option to have the IP addresses automatically chosen for this setup from the subnet’s available addresses.

Once the incoming endpoint has been created, You can set up my network’s DNS server to route requests for the amazonaws.com domain, which is used by AWS service endpoints, to the IP addresses of the inbound endpoints.

In a similar manner, you may establish an outgoing Resolver endpoint and choose Do53 as well as DoH as the protocols. Next, you design forwarding rules that specify which domains the outgoing Resolver endpoint in my network should forward queries to for DNS servers.

DNS resolutions are now secured when DNS clients in my hybrid environment utilize DNS over HTTPS in their requests. In the setting of inbound and outgoing endpoints, you have the option to impose encryption and choose only DoH.

Important information

All AWS Regions where Route 53 Resolver is available, including GovCloud Regions and Regions based in China, now support DNS over HTTPS for Amazon Route 53 Resolver.

The default DNS protocol for incoming and outgoing Resolver destinations is still port 53. Thus, unless you intend to switch from HTTPS to DNS, you don’t need to upgrade your current automated tools.

Using DNS over HTTPS with Resolver endpoints is free of charge. See Route 53 price for further details.

With Amazon Route 53 Resolver, start using DNS over HTTPS to improve security and privacy for your hybrid cloud settings.

Google Nest Mesh WiFi Router

The concept of an Interface computer was first proposed by Donald Davies for the NPL network in 1966.[17] The same idea was conceived by Wesley Clark the following year for use in the ARPANET. Named Interface Message Processors (IMPs), these computers had fundamentally the same functionality as a router does today. The idea for a router (called gateways at the time) initially came about through an international group of computer networking researchers called the International Networking Working Group (INWG). Set up in 1972 as an informal group to consider the technical issues involved in connecting different networks, it became a subcommittee of the International Federation for Information Processing later that year.[18] These gateway devices were different from most previous packet switching schemes in two ways. First, they connected dissimilar kinds of networks, such as serial lines and local area networks. Second, they were connectionless devices, which had no role in assuring that traffic was delivered reliably, leaving that entirely to the hosts. This particular idea, the end-to-end principle, had been previously pioneered in the CYCLADES network.

 diffrent router 

The idea was explored in more detail, with the intention to produce a prototype system as part of two contemporaneous programs. One was the initial DARPA-initiated program, which created the TCP/IP architecture in use today.[19] The other was a program at Xerox PARC to explore new networking technologies, which produced the PARC Universal Packet system; due to corporate intellectual property concerns it received little attention outside Xerox for years.[20] Some time after early 1974, the first Xerox routers became operational. The first true IP router was developed by Ginny Strazisar at BBN, as part of that DARPA-initiated effort, during 1975–1976.[21] By the end of 1976, three PDP-11-based routers were in service in the experimental prototype Internet.[22]

The first multiprotocol routers were independently created by staff researchers at MIT and Stanford in 1981; the Stanford router was done by William Yeager, and the MIT one by Noel Chiappa; both were also based on PDP-11s.[23][24][25][26] Virtually all networking now uses TCP/IP, but multiprotocol routers are still manufactured. They were important in the early stages of the growth of computer networking when protocols other than TCP/IP were in use. Modern Internet routers that handle both IPv4 and IPv6 are multiprotocol but are simpler devices than routers processing AppleTalk, DECnet, IP and Xerox protocols.

From the mid-1970s and in the 1980s, general-purpose minicomputers served as routers. Modern high-speed routers are network processors or highly specialized computers with extra hardware acceleration added to speed both common routing functions, such as packet forwarding, and specialized functions such as IPsec encryption. There is substantial use of Linux and Unix software-based machines, running open source routing code, for research and other applications. The Cisco IOS operating system was independently designed. Major router operating systems, such as Junos and NX-OS, are extensively modified versions of Unix software.

Network prefixes

Network prefixes

Network prefixes — is a set of IP addresses. Currently, the architecture of the Internet uses two versions of the protocol: IPv4, which consists of 32 bits, and IPv6, which consists of 128 bits. The 32-bit version of the fourth version allows the use of about 4 billion IP addresses, but even this is not enough for the Internet, which led to the appearance of IPv6. Another reason for its appearance is the address hierarchy, which simplifies routing.

Why is a network prefix needed? The aggregation size is set by the length of the prefix.

Aggregation — is the process of combining small prefixes with a long mask and a small number of hosts into large prefixes with a short mask and many hosts. Aggregation is necessary to minimize the data that the router must use when looking for a transmission path on the network.

For example, 192.50.128.0/17 determines the first 17 bits of an IP address to identify the address aggregation. The remaining 15 bits can be sub-aggregated or assigned to devices on the network to which the prefix belongs. (what network)
