Network Calculator


In order to subnet a network you need to know a few things...

	Base Network Address:			or Address:	
	Network Netmask:			or CDIR:	
	Netmask Wildcard:			
	Broadcast Address:			
	Network Minimum Address:	
	Network Maximum Address:	
	Hosts Per Subnet:		

IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range.

Enter your netmask(s) in dotted decimals ( or CIDR notation (/25).

The class of your network is determined by its first bits.

The wildcard is the inverse netmask as used for access control lists in Cisco routers.
