About Class C Ip Checker


The Class CIP Checker is easy to use. Simply enter the domain names of the sites you wish to identify the Class CIP in the text area. Click the "Get Info" button after entering the domain names into c class IP looker. The utility will run the test, and then return the results.

  • You can enter up to 20 domains in the Text Area. Each Domain must be on a separate line.
  • Click the "Get Info" Button

C class IP Checker will display your host names. It will also display each hostname's IP address, Class CIP, and status.

These results will display the hosts sharing the same IP class C. If the status is valid, then everything should be fine. This tool allows you to check if other websites share the same IP addresses.


Each device connected to the internet has its own unique IP. Each node in a distributed network, such as the internet, is assigned an address to enable systems to find each other.

This address is also known as an 'IP address', or simply 'IP'. It is 32-bit binary and consists of two sub-addresses which identify the network's host and the network's network. The IP address is made up of four numbers, ranging from 0 through 255 and separated by a (.). in decimal form. For example, can be considered a valid IP.


There are five classes of IP addresses. Our concern is IP Class C, which is:

  • Class A

    The class A address's first bit is always set at 0. The network portion of an address is left empty with seven bits. The Class A addresses are between and This means that there can only be 128 network number.

  • Class B

    The class B address's first bit is always set at 1 while the second bit is set at 0. This means that 16,384 networks could be assigned class-B addresses. These numbers are between and

  • Class C

    The first two bits of Class C addresses are set to 1 and the third bit to 0. This means that 2,097.152 networks can be assigned this type of address. These numbers can be found between and Example of a Class C IP address is 123.789.456.1

  • Class D

    The first three bits of Class D addresses are set to 1 and the fourth bit to 0. Multicasting applications use Class D addresses. These numbers are reserved for multicast groups and range in frequency from to

  • Class E

    Classes E addresses are for experimental and testing purposes only and have never been used in any standard form.


Classes A and B are reserved for very large and medium-sized businesses. The most commonly assigned addresses to small businesses is Class C. They are also the most frequently used IPs. Internet service providers of small and medium size purchase class C IP that they then assign to their customers. Internet service providers offer dynamic (shared IP addresses) to customers. Because they are shared, they can be cheaper and more widely used. Second, IP addresses are not used 24/7 by the users who have been assigned them. If a user signs off or there is not enough traffic to a website their IP addresses are given to other users and websites.

C class dynamic IP addresses have the advantage of being more affordable and easier to use for websites and users who don't use the internet often. You will receive a dynamic address if you have five people using your WiFi. When you sign out, your address will be assigned automatically to another user. You will receive a new IP when you log in again to the internet. The available class C IP range will provide the IP.


The Class C IP Checker tool identifies if the same class C IP address is shared by multiple domains using shared hosting. It can also be used to locate duplicate IP addresses of class C blocks.

There are risks associated with dynamic class C IP blocks as they are shared across multiple nodes. Your website could get blacklisted if it has a dynamic C-class IP address. This can impact your website's search engine ranking and make your SEO efforts less effective. Your website could also be blacklisted if a website sharing your IP address is blacklisted. This happens when a search engine blacklists websites. It doesn't blacklist a website based on its domain name only, but also its IP address. Because the IP address is unique identifier for the domain, search engines visit websites by visiting its IP. This possibility is foreseen by internet service providers. If a website is blacklisted, they assign a new IP to other websites sharing the same dynamic C IP address range.

To ensure their hosting services provider systems are protected from malicious attacks, internet service providers install firewalls. Internet service providers must take steps to protect their hosting services and networks from hackers and other malicious individuals, as they are continually targeted by hackers.


You will want to find out which websites share the same Class C IP if you just bought a website hosting service. It's likely that your website was assigned this class of IP address, and that it is shared with other sites.

This handy tool can be used by to perform a class-C IP address check at any time.


  • If spam sites share the same IP address as class C blocks, it helps to identify them.
  • It is possible to find duplicate IP addresses as well as IP addresses for class C blocks.
  • You can block a domain that is involved in suspicious activities and take the necessary steps to prevent your site from being banned. Your search engine ranking will be secured by regularly checking your domains with the Class C IP Address Checker tool.

You can also run bulk c-class ip checks. You can check the c class IP from various websites on the internet. This will tell you if websites are safe and if they have the right tools to protect them against spam and viruses.
