One, iproute2 is maintained. net-tools isn't.

Unmaintained key system tools are a security and reliability risk that
can IMO not be justified by merely not wanting to move on. IIRC,
net-tools has been orphaned since 2003.


Two, the iproute2 tools are lighter-weight than the net-tools ones,
on account of using netlink instead of procfs and ioctl.


Three, UI is more intuitive. (Yes, you say you are already used to
what you're familiar with. I used to say this about nslookup.)
The various iproute2 tools have a consistent syntax and are
scripting-friendly.


Four, iproute2's ip command can add/manage/display multiple IP addresses
on a single interface. net-tools can only semi-approach this
functionality via IP aliasing.

The 'display' functionality of the net-tools toolkit is particularly
broken in that department. 'ifconfig eth0' will show only one IP
address. 'ip addr show dev eth0' will show all of them.


Reason number 1 is sufficient, IMO.

Why do you make this claim without bothering to do your homework?
