For some unknown reason, although IHETS has been allocated the entire traditional class B 165.138.0.0, they are announcing it as a partial 165.138.0.0/20. They could announce the entire /16. But they've chosen not too. If IHETS wants to ensure they can reach as much as the Internet as possible, they could follow Sprint's filtering policy, and announce their network as a 165.138.0.0/16. IHET could check http://www.sprint.net/filter.htm for a description of the policy. Since IHETS seems to be a SPRINT customer, I sure would appreciate it if the SPRINT NOC could explain to IHETS why such address filters exist, and if Sprint thinks its a good idea to apply them to other ISPs, why the reciprocal argument would also be true. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation
