If you check the man page of Netstat you will find these lines.
This program is mostly obsolete. Replacement for netstat is ss.
Replacement for netstat -r is ip route. Replacement for netstat
-i is ip -s link. Replacement for netstat -g is ip maddr.
You can also find some replacements table from this google spreadsheet link.
I am not going to talk about the legacy command of “netstat“. The purpose of this article will be about “ss“.
