There is, in fact, excellent documentation on their site for this https://libera.chat/guides/cloaks.

Of course, it's not as much of a free-for-all as some other networks (I recall Rizon lets you set whatever cloak you want), but it should hide hostnames.

by default, Rizon replaces the identifying part of your hostname with "Rizon-xxxxxxxx"... I wish that liberachat would do the same without needing to register and then take some other action.... I don't need a custom hostname, just one that doesn't broadcast my IP.
