I'm not 100% sure whether this is the correct forum to announce changes in ARPANET/Internet addressing, but hopefully those who are not on the Internet will forgive my intrusion for the sake of getting the word out to as much of the Internet as possible. The UCLA CS Department will be undergoing a major network reorganization on Monday (3/27). *ALL* the machines in the CS department will get new Internet (numeric) addresses -- changing from addresses in 128.97 to a completely new set of addresses in the 131.179 network. We will start taking machines down around 0900 PDT on Monday; most should be back up by around 1200; virtually all should be running again by day's end, with isolated stragglers taken care of on Tuesday. This change will affect *only* hosts whose official names end in "CS.UCLA.EDU". Other UCLA machines, not in the CS Department, will be unaffected by the change. The change is not simply a replacement of "128.97" by "131.179"; we are reorganizing our subnet structure, as well as the host addressing within each subnet. There is no way to predict a host's new address on the basis of the old address; don't bother trying. The host *names* will not be changing -- only the numeric *addresses*. Hence, you won't need to change your UCLA e-mail addressing habits in any way whatsoever. If you use the domain data base, you hopefully won't need to take any particular action in response to this change. Our resource records have been going out with 6-hour TTL's for some time now. If you are still stuck with the NIC Host Table or a derivative thereof, you may wish to take note that the Internet address for CS.UCLA.EDU (the host name which is used in all of our department's outgoing e-mail) will change from "128.97.28.20" to "131.179.128.13". -- Rich Wales // UCLA Computer Science Department // +1 (213) 825-5683 3531 Boelter Hall // Los Angeles, California 90024-1596 // USA wales@CS.UCLA.EDU ...!(uunet,ucbvax,rutgers)!cs.ucla.edu!wales "I couldn't read it because my parents forgot to pay the gravity bill."
