Enter up to 40 Domains (Each Domain must be on separate line)
The Class C IP Checker is very easy to use. Simply type the domain name of the sites you wish to find the Class C IP for in the text box. Click the 'Get Info' button after inputting the domain names in the c class IP checker. The test will be done and the results will be returned by the utility.
In the text area, you can enter up to 20 domains (Each Domain must be on a separate line)
Select "Get Info" from the drop-down menu.
C class IP checker will display the hostnames that you supplied in the results, along with their IP address, Class C IP, and status for each hostname.
IP ADDRESS CLASSES
There are five classes of IP addresses and our concern is with IP Class C which are:
The first bit of a class An address is always set to 0. It only leaves seven bits for the network portion of the address. Class A addresses range from 0.0.0.0 – 127.0.0.0. It means there can only be 128 network numbers.
The first bit of a class B address is always set to 1 and the second bit is set to 0. It means 16,384 networks can be assigned class B addresses. The numbers range from 22.214.171.124 – 126.96.36.199.
Class C addresses have their first two bits set to 1, and the third bit is set to 0. It means 2,097,152 networks can be assigned this class of address. The numbers range from 192.0.0.0 – 188.8.131.52. Class C IP Address Example is 123.789.456.1
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 multicasting applications. The numbers range from 184.108.40.206 – 220.127.116.11 and are reserved for multicast groups.
Class E addresses are reserved for experimentation and testing and have never been utilized in any standard form.
WHAT IS A CLASS C IP ADDRESS?
Class A and B are assigned to very large and medium-sized organizations. Class C is the most popular class of addresses assigned to small companies and is the most used IP. Small and medium-sized internet service providers purchase a pool of class C IPs that they assign to their customers. Internet service providers provide dynamic (shared) IP addresses to their customers. The reason for this is that since they are shared, they are cheaper and more popular. Secondly, the users that are assigned IPs do not use them 24/7. So when a user signs of or there is no traffic to a website, their IP addresses are assigned to other users and websites.
The pros of C class dynamic IP addresses are that they are cheap and more feasible for websites and users who are not heavy users of the internet. If you have five people sharing WiFi 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 just signs in. When you use the internet again, you will be assigned a different IP. This IP will be assigned from the available pool of class C IP address range that your internet service provider has purchased.
