Subnetting

Subnetting is the process of dividing a block of IP addresses assigned as a Class A, B, or C network into multiple smaller blocks of addresses.


This hour addresses the needs and benefits of subnetting, as well as the steps and procedures you should follow to generate a subnet mask.

Find IP Address

We have launched this web site not only to help you check IP address and find out what is my computer IP number or what is my IP address but also help you to trace, track, locate and get any computer IP address in the world.

Our totally free IP location tracker and IP number lookup service (aka IP checker) use high quality IP database to determine and show IP location on world map along with information's such as IP postal code or IP zip code (available only for IP addresses from USA and Canada), IP latitude, ISP, Organization...

Find IP Address team give you also possibility to find, check, trace and track any other location based only on IP number.






CIDR - Subnet masks

CIDR

Class A addresses are long gone, and the world is quickly running out of Class B addresses. Many Class C addresses are still available, but the small address space of a Class C network (254 hosts maximum) is a severe limitation in the high-volume game of Internet service providers (ISPs).



It is possible to assign a range of Class C networks to a network owner who needs more than 254 addresses. However, treating multiple Class C networks as separate entities when they are all going to the same place only clutters up routing tables unnecessarily.

Classless Internet Domain Routing (CIDR) is a technique that allows a block of network IDs to be treated as a single entity in routing tables. CIDR groups a range of network IDs into a single address entry using what is called a supernet mask.

You can think of a supernet mask as something like the opposite of a subnet mask. Instead of designating additional bits for identifying the network, the supernet mask in effect takes bits away from the network ID. The addresses in the range are therefore identified by the network address bits that the networks in the range hold in common.

Subnet Calcuator

Subnets calculator will calculate numbers of subnet for ip address range and make CIDR summarisation for given ip address. CIDR Ranges format (CIDR summarisation) is very useful if you need to block some ip ranges on your server using .htaccess
