Broadcast and default gateway

Hello,
Please consider the following output:
Code:# ip address show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

inet6 fe80::a62:66ff:fec8:c3e8/64 scope link noprefixroute

Thank you.
