how to change ifconfig lo0

Question

my ifconfig lo0 looks like this:

lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
options=1203<RXCSUM,TXCSUM,TXSTATUS,SW_TIMESTAMP>
inet6 ::1 prefixlen 128
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1
inet 192.168.10.11 netmask 0xffffff00
nd6 options=201<PERFORMNUD,DAD>

I need to add inet 127.0.0.1 netmask 0xff000000. How can I do it ?

Answer 1

Run this command in the Terminal:

ifconfig lo0 127.0.0.1/8

Or if you want to keep your current (odd) address for the lo0 interface, then add 127.0.0.1 as an additional (alias) address with:

ifconfig lo0 alias 127.0.0.1
