Hmm, I thought my host here was on a LAN..
vmx0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
inet 216.250.176.100 netmask 0xffffffe0 broadcast 216.250.176.127
inet6 2001:4980:2:dad::100 prefixlen 64
And this one too..
bce0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
inet6 2001:4980:0:1000:21e:c9ff:feb5:663a prefixlen 64 autoconf
inet6 2001:4980:0:ffff:21e:c9ff:feb5:663a prefixlen 64 autoconf
Are you sure your definition of "LAN" is the correct term?
What is it you are trying to determine?
