Need help with dedicated server setup!

I am trying to set up a dedicated server but for some reason people can’t connect, i am not behind a router so then we got that problem out of the way, i have two problems:

When starting up i get this message:

NET_GetBindAddresses found ‘Marvell Yukon 88E8053 PCI-E Gigabit
Ethernet Controller’
Network: IP unknown, mode MP, dedicated Yes, ports 27015 SV / 0 CL

IP Unknown is what i am wondering about.

2: when i write “ip” it says:
Lol wat.

How do i know that other people can connect to it?

Anyone know any solutions?
