Within a subnet, what address should a router be installed.

Use this calculator when you know your IP number and Subnet Mask and want to find out the correct Router Address, Network Address, and Subnet Broadcast Address. If you think that it would be especially nifty for this calculator to figure out anything else let them know what it is and they will give your idea a spin.

Note: Wharton Network Engineering has chosen a standard Router address at the network address plus one. For instance, if the local network is 127.100.100.0, then the Router would be 127.100.100.1, or if the local network number were 127.100.100.128 then the Router would be 127.100.100.129. Do not rely upon our standard for networks outside of Wharton which could easily follow some other standard, or no standard at all!

ie: It is common for admins to use 192.168.1.254 for the gateway / router and 192.168.1.1 for the DNS server etc.
