Anarplex runs several I2P eepsite destinations. They are:
For web access: anarplex.i2p vqzl5bevmzz6vh4d3rjfoxa2wfmhdb76qfgkx5a3r3uwiw6a4ooq.b32.i2p
For IRC access: agora.anarplex.i2p eplpiyfwgnq74wbfveughu2l2kdzvcriaovjjbgn5zwe7pgmtyzq.b32.i2p
If you are running i2pd add these lines to your ~/.i2pd/addressbook/addresses.csv :
agora.anarplex.i2p,eplpiyfwgnq74wbfveughu2l2kdzvcriaovjjbgn5zwe7pgmtyzq anarplex.i2p,vqzl5bevmzz6vh4d3rjfoxa2wfmhdb76qfgkx5a3r3uwiw6a4ooq
And this to your ~.i2pd/tunnels.conf :
[agora.anarplex-out] type = client address = 127.0.0.1 port = 6667 #destination = agora.anarplex.i2p destination = eplpiyfwgnq74wbfveughu2l2kdzvcriaovjjbgn5zwe7pgmtyzq.b32.i2p keys = agora.anarplex.dat
You can then connect your IRC client to 127.0.0.1:6667 to connect to the IRC server.
