For many years we (or more precisely the folk at University of Waikato who used to operate the first international Internet gateway and later the first exchange point in NZ) tracked IP addressess in NZ. We did this so we could bill NZ traffic at a different rate to International traffic. They got the information from the routing tables rather than from the NIC data bases. What we found was that as soon as the big ISPs go involved we started seeing /30, /31 and /32 bits of addresses that were supposedly in Australia and US popping up here. These addresses were often allocated to routers and the likes so the graphical tools would show traceroutes between two NZ addresses going via the US. BTW we have given up trying to track down 'local' address blocks now, they are just to fragmented and there is nolonger any single place where everone peers. -- Russell Fulton, Computer and Network Security Officer The University of Auckland, New Zealand --------------------------------------------------------------------- To unsubscribe, e-mail: loganalysis-unsubscribeat_private For additional commands, e-mail: loganalysis-helpat_private
