Take a pick wisely!

Some of those have valid certificates

nmap -Pn -sV -p 6679,6697 ssl.irc.atw-inter.net -T4
nmap -Pn -sV -p 6679,6697 barjavel.freenode.net -T4

other Freenode server names

chat.freenode.net

other Online/EvoluNET server names

irc.dedibox.fr irc.evolu.net irc.online.net

62.210.159.99
    autrechose.evolu.net free-vitry.fr.eu.evolu.net online-dc2.fr.eu.evolu.net

62.210.156.11
    autrement.evolu.net online-dc3.fr.eu.evolu.net

EFNet host .dk is cool but it does not let us connect

    Subject: CN = efnet.deic.dk
            DNS:efnet.deic.dk, DNS:efnet.deic.eu

so all we have is EFNet host .nl with its dirty self-signed certificate (there’s no DANE there, is there?)

    Subject: C = NL, L = "Amsterdam, The Netherlands", O = Eris Free Network (EFNet), CN = irc.efnet.nl, emailAddress

= admin@irc.efnet.nl CA:TRUE

we could still try -tls_pinned_cert for this particular situation.

Librea

Subject: CN=rhenium.libera.chat
            DNS:irc.ipv4.libera.chat, DNS:irc.ipv6.libera.chat, DNS:irc.libera.chat, DNS:rhenium.libera.chat
