Enter up to 40 Domains (Each Domain must be on separate line)
In order for systems to locate each other on distributed networks, such as the Internet, each node in the network is assigned a unique address.
The IP address is a 32-bit binary address that consists of two sub-addresses that identify the network and the network host. The IP address consists of four sets of numbers ranging from 0 to 255 separated by a (.) In decimal form. For example, 188.8.131.52 is a valid IP address.
IP address classes
There are five kinds of IP addresses that are:
The first bit of a class An address is always set to 0. It only leaves seven bits for the network part of the address. Class A addresses range from 0.0.0.0.0 to 127.0.0.0.0. This means that there can only be 128 network numbers.
The first bit of a class B address is always set to 1 and the second bit to 0. This means that class B addresses can be assigned to 16,384 networks. The numbers range from 184.108.40.206.0 to 220.127.116.11.
Class C addresses have their first two bits set to 1, and the third bit is set to 0. This means that 2,097,152 networks can be assigned to this address class. The numbers range from 192.0.0.0.0 to 18.104.22.168.
Class D addresses have their first three bits set to 1, and the fourth bit is set to 0. Class D addresses are used for multicast applications. The numbers range from 22.214.171.124.0 to 126.96.36.199.255 and are reserved for multicast groups.
Class E addresses are reserved for experimentation and testing and have never been used as standard.
What is class C IP?
Classes A and B are assigned to very large and medium organizations. Class C is the most popular class of addresses assigned to small businesses and they are the most used IP addresses. Small and medium-sized Internet service providers acquire a set of class C IP addresses that they assign to their customers. Internet service providers provide dynamic (shared) IP addresses to their customers. The reason for this is that when shared, they are cheaper and more popular. Second, users who are assigned IP addresses do not use them 24 hours a day, 7 days a week. So when a user signs or there is no traffic to a website, their IP addresses are assigned to other users and websites.
The advantages of class C dynamic IP addresses are that they are cheap and more feasible for websites and users who are not large Internet users. If you have five people who share a WiFi connection in your home, you will be assigned a dynamic address, and when you are not using the Internet, your address will be assigned to another user who has just logged in. When you use the Internet again, you will be assigned a different IP address. This IP address will be assigned from the available set of class C IP addresses that your Internet service provider has acquired.
As Class C dynamic IP addresses are shared between several nodes, there are dangers associated with them. If your website has a dynamic class C IP address, it can affect the ranking of your website in search engines and your SEO efforts could be wasted. If a website that shares the same IP address as yours is blacklisted, your website may also be blacklisted. This happens when a search engine blacklists a website. It does not include a website on a blacklist only by its domain name, but also by its IP address. Search engines when they visit a website do so by their IP address, since the IP address is the unique identifier of the domain. Internet service providers provide for this possibility and, if a website is blacklisted, they reassign new IP addresses to other websites that share the same dynamic Class C IP address.
Internet service providers install firewalls and other applications and hardware necessary to ensure that their hosting service provider systems remain "clean" and are not affected by malicious attacks. As hackers and other malicious people constantly try to enter and damage websites, Internet service providers are forced to take measures to protect their networks and hosting services.
