You could get the answer with one single command:

% ip addr list dev lo
1: lo:  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
    inet 127.0.0.1/8 scope host lo
    ^^^^^^^^^^^^^^^^
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host
    ^^^^^^^^^^^^^
       valid_lft forever preferred_lft forever
