Strange foreign connections

[Gene]

While running netstat I found these entries:

Active Internet connections (including servers)
Proto Recv-Q Send-Q  Local Address          Foreign Address        (state)
tcp4       0      0  localhost.52730        undernet1.blueyo.ircd   
ESTABLISHED
tcp4       0      0  localhost.52398        minotor.spale.co.ircd    
ESTABLISHED
tcp4       0      0  localhost.60635        bagan2.srce.hr.ircd       
ESTABLISHED
 

  The foreign addresses all show ircd at the end,  but there is no irc 
clients or servers running and irc ports are blocked at the firewall.
Does anyone have any idea what might be going on here?
