204.245.240.64 |
204.245.240.64/26 |
CIDR notation, which shows that a block of IP addresses belongs to a specific backbone provider. This lets larger Internet routers use a single IP address to represent all of the thousands of addresses serviced by a that backbone provider. Instead of having to recognize each individual IP address, the router now needs only determine which provider "owns" the block of IP addresses. The CIDR notation in the example is a "shorthand" which specifies all IP addresses of this classless subnet: 204.245.240.64 - 204.245.240.127. |
