Are you referring to the /whois command on IRC? If so, that returned the IP address of the user and not the server.

Simple solution! Just went through the same thing and got a fix for you.

Go and edit the vhost file.

sudo nano /etc/hosts

After you open it you should add this after the 127.0.0.1

0.0.0.0    example.com

And add this after ff02::3 ip6-allhosts

2001:4860:4860::8888   example.com

Then go into the ZNC Web Interface; Go into Your Settings Above the Quit Message you should see BindHost put your domain.

• Make sure you change example.com to vc-mp.co.uk
