IPv6 vHosts and IRC Server Compatibility
Many Eggy vHosts use IPv6.
An IPv6 vHost requires the external IRC server to accept IPv6 connections.
If the selected IRC server supports IPv4 only, the network may fail to connect while an IPv6 vHost is active.
Recommended presets
For Undernet:
For QuakeNet:
These use the networks' IPv6-capable server addresses.
Common problem
Using:
with an IPv6 bindhost may resolve to an IPv4-only route and prevent the connection.

What to check
If the network cannot use IPv6, choose an available IPv4-compatible vHost or server configuration.
Changing the server or vHost may require the affected network to reconnect.

Use the
irc6.* address where required.What to check
- Whether the active vHost uses IPv6.
- Whether the external IRC server has an IPv6 address.
- Whether the selected server and port are currently valid.
- Whether the dashboard preset uses an
irc6.*server.
