192.168.1.100 is the beginning of the default dynamic IP

address range for Linksys home network routers. This means

the first computer (or other device) you attach to a Linksys

router will typically be assigned the address 192.168.1.100

by DHCP. You can change the DHCP range of a router through

its configuration utility to either use or not use

192.168.1.100.
