A router routes traffic between different subnets. It has an ip address on
each network. You tell your computer how to A. get out of your subnet to find
all the others, or B. to find one or more specific subnets.

A bridge connects different network topologies, like fiber and twisted pair,
and does not have any ip address.

Now you cannot use a bridge as a router, again due to the fact that it does
not have an ip. You cannot say go to this ip to get to someplace.

Now, things are changing as people realizes things you can do by mixing up
these features. F.ex. in OpenBSD you can have a bridge as a firewall. It's
now a firewall that you cannot reach from the network so it's very safe.

It's also an excellent way of firewalling off a portion of your network by
invisibly inserting it f.ex. outside the accounting network.
