Once i was attacked by a mailbox bomb. I hv a code in Perl. Bt can anyone

[abhi]

tell me how he got my ip?
My extended info to colinic n jerry B:-

i hv code in perl with which just randomly ip add..s can b found out.
I dont kno how to send a mailbox bomb.
I thought it req ur ip.
That peson was continuosly asking me 4 some thing which i didnot want to gve. It was a file. I just told him sme thing bad , then i was attacked. The packets were so much that I lost my connection. I thought as long as i do not interact wth the his code , my ip wont be known. Thats why i asked da ques. But u say ip is nt req. Then i think i hv been answered.
