Ah yes, that makes sense. In order to support IPv6, I map IPv4 addresses into IPv6 so that I do not have to care later about it.

It would be nice if the command took hostnames, too, but that didn’t work in my tests and so I reverted the commit:

https://git.ipfire.org/?p=fireperf.git;a=commitdiff;h=0ec017a4da5e00c405d63782d34009f486dc9478
