Determining Subnet Mask

>> Network Tasks

On host do:

ifconfig -a

On tauceti the output looks like:

tauceti:ktah% ifconfig -a
lo0: flags=1000849 mtu 8232 index 1
inet netmask ff000000
eri0: flags=1000843 mtu 1500 index 2
inet netmask ffffff00 broadcast
lo0: flags=2000849 mtu 8252 index 1
inet6 ::1/128
eri0: flags=2000841 mtu 1500 index 2
inet6 fe80::203:baff:fe2f:a6ee/10

whose subnet (netmask) is ffffff00 in hex or in octet (TJ).
