First off - take the IP address and go match it in the Ripe database (www.ripe.net ) to find
out who owns it. Ripe may send you to ARIN or APNIC ( US and Asia/Pacific equivalent databases )
Once you know who owns it you should have an admin contact for the address range.
They normally have an 'abuse@' email address that you should contact.
If it's an IP address from somewhere in ireland, then the admin's for the address range are
probably reading - but what can they do ?
Let's assume that it was my address that probed you - I'll just claim to anyone that emails
me that it was a violated windows machine on the network. :-)
Our office firewall is probed continually - you might consider looking at fightback as part

I suspect that unless something more than a probe has happened, the gardai won't be
the slightest bit interested .. and even if the were - what can they do ? Arrest someone
because a machine somewhere on the net sent some packets ? You'd need to be
broken into - and damage to have occurred before I'd expect the gardai to do anything
more than point you at ripe themselves :-)
