linux - ip versus ifconfig


After reading this answer, I began my quest for the difference between ip and ifconfig for *nix systems. I soon learned that ip had "more" features than ifconfig, but what's the real difference? Is there any reason not to use ifconfig when it provides the functions I need? (E.g. security implications) Like to know since I'm an avid ifconfig user.



Answer



Simple answer: On Linux ifconfig is obsolete.


From man ifconfig:



This program is obsolete! For replacement check ip addr and ip link. For statistics use ip -s link.
