What “address is banned” means
address is banned usually means the IRC channel or network has a ban mask that matches your current identity.
IRC identity is commonly matched as:
nick!ident@host
A ban can target your nickname, ident, host, IP, vhost, services account state, or a broad BNC/VPS range.
This does not always mean Eggy BNC is broken
If you can connect to the network and join other channels, the BNC is working. The failed channel is applying its own rules.
Common ban examples
*!*@host.example
*!~*@*
*!*@77.68.*
*!*@*.eggy.net
Some channels ban unverified ident users, hosted users, public BNCs, or broad ranges.
What you can try
Check whether the channel requires registration, invite, services account login, or a different nickname. Changing vhost may help in some cases, but it is not guaranteed.
What support can and cannot do
Eggy BNC support can help you understand your visible hostmask and settings. It cannot force another channel or network to remove a ban.
