Re: Has PSI been assigned network 1?
We don't trust our peers. We only accept routes which they are registered as providing transit for in the PRDB. When the RADB is in use, unless PSI has a route object for 1.0.0.0/8 in the RADB, we still won't trust them when they try to pass us 1/8.
Then you're back to the www.pizzahut.com(192.112.170.243) example. Reachable from most places as long as you don't touch NSFNET/ANSNET and the PRDB. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation

We accept that. If pizzahut wants to reach a wider community, they can ask their provider to register their route in the RADB. From a routing standpoint all it needs is the prefix, prefix length, and the home-AS. As long as prior policy existed for the home-AS or the home-AS can be associated with an AS macro for which policy is defined. A given provider can register an AS macro for their direct customers that have their own AS. No more NSF AUP to worry about. If not, its pizzahut's loss.

BTW- Is pizzahut the most valuable resource you could come up with that is not reachable from ANSNET? Once we are free of the AUP, we can also register specific networks with the RADB at our customer's request and the other guys approval even if their own provider is too stuborn to do so. We'll see if we get any urgent requests to register Pizzahut's class C address. We can do this now, but Pizzahut probably can't justify use for research and education and has a provider that doesn't have an agreement with ANS to carry commercial traffic (as required by the NSF for purely commercial traffic and heartily supported by the OIG in their 1993 review of the NSFNET program).

Right! Case in point that there is some benefit you may get from registereing in the routing registry. Another benefit would be more meaningful output from tools like prtraceroute: --- reif!dfk 95> pt 192.112.170.243 ** WARNING ** Destination AS unknown for www.pizzahut.com (192.112.170.243) ** WARNING ** Policy information is not possible - setting to "?" traceroute with AS and policy additions [Apr 20 09:56:34 UTC] from AS3333 reif.ripe.net (193.0.0.131) to ??? www.pizzahut.com (192.112.170.243) 1 AS3333 insomnia 193.0.0.142 [?] 3 2 2 ms 2 AS3333 Amsterdam 193.0.0.222 [?] 28 3 3 ms 3 AS1128 Amsterdam1.Dante.net 192.87.4.35 [?] 43 10 5 ms 4 AS1804 icm-dante.icp.net 194.41.0.18 [?] 125 95 87 ms 5 AS1800 icm-dc-1-E4/2.icp.net 192.157.65.73 [?] 141 90 102 ms 6 AS1800 Boone1.VA.ALTER.NET 192.157.65.227 [?] 246 239 232 ms 7 AS701 Dallas1.TX.ALTER.NET 137.39.128.7 [?] 251 263 ms 8 AS701 Pizzahut-gw.ALTER.NET 137.39.227.226 [?] 321 318 302 ms 9 ??? www.pizzahut.com 192.112.170.243 [?] 312 315 298 ms AS Path followed: AS3333 AS1128 AS1804 AS1800 AS701 ???
