7.6.1   IP Interfaces
The switch needs an IP address for it to be managed over the network. The factory default IP 
address is 192.168.1.1. The subnet mask specifies the network number portion of an IP 
address. The factory default subnet mask is 255.255.255.0.
On the switch, as a layer-3 device, an IP address is not bound to any physical ports. Since each 
IP address on the switch must be in a separate subnet, the configured IP address is also known 
as IP  interface (or routing domain). In addition, this allows routing between subnets based on 
the IP address without additional routers. 
You can configure multiple routing domains on the same VLAN as long as the IP address 
ranges for the domains do not overlap. To change the IP address of the switch in a routing 
domain, simply add a new routing domain entry with a different IP address in the same subnet.
