Class B allows for 16,384 networks by using the first two octets for the network ID.

Number of Hosts per Network: 16,777,214Ĭlass B Public & Private IP Address RangeĬlass B addresses are for medium to large sized networks.

Private IP Range: 10.0.0.0 to 10.255.255.255 (See Private IP Addresses below for more information).

Class A network number values begin at 1 and end at 127. The 24 bits in the remaining three octets represent the hosts ID and allows for approximately 17 million hosts per network. The remaining seven bits in this octet complete the network ID. The first bit in this octet, is always zero. Class A allows for 126 networks by using the first octet for the network ID. Class A Public & Private IP Address RangeĬlass A addresses are for networks with large number of total hosts.

The four octets that make up an IP address are conventionally represented by a.b.c.d - such as 127.10.20.30.Īdditionally, information is also provided on private addresses and loop address (used for network troubleshooting). The list below shows the five available IP classes, along with the number of networks each can support and the maximum number of hosts (devices) that can be on each of those networks. Class D and class E are for special uses. Primarily, class A, B, and C are used by the majority of devices on the Internet. Each class has a specific range of IP addresses (and ultimately dictates the number of devices you can have on your network). In the IPv4 IP address space, there are five classes: A, B, C, D and E.
