Hi all,
last night i had an dos attack on my mailserver and i would like to find
out who it was. It was coming from the level3.net network but since this
is an international isp who sells his service to local isp i can not
find out more on my own.
The attack was coming from austin1.level3.net with the IP 64.154.144.247

Am i right to say austin1 means Austin, TX?
Thank you for any help
