It can be set using ip link set dev <interface> mtu <value>, where <interface> is the interface name. ip link set dev enp0s31f6 mtu 1400 would set the MTU of emp0s31f6 to 1400 bytes. Should I change it? Generally speaking, no.Tue, 14 Apr 2026 19:07:00 GMThttps://askubuntu.com/questions/607497/what-is-the-difference-between-pinging-loopback-address-and-pinging-the-systemsThe two are on different "interfaces" - the lookback address is on the loopback interface which should be present always (unless you've done something really freaky with your config).
