Others have answered the technical issues.
If you just want to run ifconfig because its output pleases the eye
(perfectly reasonable if you been using it for years), you can just
run it as a user, not root. Type, say,
$ /sbin/ifconfig -a
to display all interfaces. That way, you shouldn't be able to disturb
your networking by reconfiguring it accidentally.
If you *want* to configure it, use ip instead. Most people will not be
willing to help with ifconfig any more. It's obsolescent, and doesn't
handle a lot of modern configuration options.
Cheers,
David.
