what is the subnet for 192.168

http://www.pantz.org/software/tcpip/subnetchart.html

Ths is an Internet Protocol (IPv4) Subnet Chart. You can use this to quickly look up how your might need to subnet your network. At the bottom there is a quick how-to on calculating subnets.

For more information on subnetting, see RFC 1817 and RFC 1812.

Class address ranges:

• Class A = 1.0.0.0 to 126.0.0.0
• Class B = 128.0.0.0 to 191.255.0.0
• Class C = 192.0.1.0 to 223.255.255.0

Reserved address ranges for private (non-routed) use (see RFC 1918):

• 10.0.0.0 -> 10.255.255.255
• 172.16.0.0 -> 172.31.255.255
• 192.168.0.0 -> 192.168.255.255

Other reserved addresses:

• 127.0.0.0 is reserved for loopback and IPC on the local host
• 224.0.0.0 -> 239.255.255.255 is reserved for multicast addresses

Chart notes:

• Number of Subnets - "( )" Refers to the number of effective subnets, since the use of subnet numbers of all 0s or all 1s is highly frowned upon and RFC non-compliant.
• Number of Hosts - Refers to the number of effective hosts, excluding the network and broadcast address.
