I'm customer of an Irish ISP, eircom, which has started censoring the pirate bay.
When I try to ping
18.104.22.168 which is the IP address of thepiratebay.com, I get this output:
PING 22.214.171.124 (126.96.36.199) 56(84) bytes of data. From 188.8.131.52 icmp_seq=1 Packet filtered From 184.108.40.206 icmp_seq=2 Packet filtered From 220.127.116.11 icmp_seq=3 Packet filtered
How does ping know that's it's filtered? How can I learn more about how it's filtered. My ping/nmap foo is weak.
