In preparing for this edition, ifconfig still worked well on our testing
system, but it was no longer installed by default. It is losing favor as ip sees
more use. This command works with a series of subcommands to perform its
tasks. Many of the common subcommands also have short aliases, which are
also listed here. Note that the IP addresses listed below are examples; the
addresses in your network will likely be different.
The following command allows you to get information about all your network
