No, I’m not a wizard.

I’m in banning more IP addresses from referral spammers today and have a little time for a quick aside. In the last week, I’ve been asked to help with several home networks. Three times I’ve been asked how in the world I knew what the routers’ IP addresses were.

I’m not a wizard… There are three options for “internal” networks. Your router has an outside IP address that is visible to the world. I won’t know what that one is unless you hit ipchicken.com and tell me what it is.

The three options for internal networks are the following ranges of IP addresses:

10.0.0.0 – 10.255-255-255. This range of addresses is typically used by Apple devices as the default. So your router, unless you have changed it, will usually be 10.0.1.1

172.16.0.0 – 172.31.255.255.  I have never run across a router in the wild that uses this range by default, but there probably are some.

192.168.0.0 – 192.168.255.255. Linksys usually runs in this range and the router address for their most popular models generally comes in at 192.168.1.1.

See, no magic.

If you want to check and see what the router address is, open a cmd window and type in “ipconfig” without the quotes. The default gateway will be your router. If it says nothing and it also says your ip address is 127.0.0.1, it means you have no network connection. 127.0.0.1 is the “local loopback” address that your computer gives itself if it can’t connect to a network.
