IP Address Shortage

A private IP address is most probably an IP address of a home router

It is the most popular IP address used for a home router. Actually most of the routers have the address set by default.

The home router usually serves also as a DNS and a DHCP server for the home network.

In binary form it is 11000000101010000000000100000001 or 0b11000000101010000000000100000001.

In hexadecimal format it is C0A80101 or 0xC0A80101.

As the netmask of those networks is usually 24 bits, the address is written also as or
