How does uml interact with its host using a lan?

The most common way is with tuntap. Upon launching uml, one assigns an ethernet address to uml, and once executing uml, brings up its ethernet connection.
Ex. linux eth0=tuntap,,,192.168.0.254
And once inside uml:
ifconfig eth0 192.168.0.253
(Note the difference in ip address)
