Any chance we could have some 10BaseT along with the thin coax? Then I can leave my coax dongle at home. Thanks in advance for better connectivity. --Kent

Two ASN 99s
by Bill Woodcock 17 Oct '96

17 Oct '96

This is probably a really stupid question, but why are there two ASN 99s? Was ASN 99 recycled or reassigned or something? I did a really quick uniq through the ASN list, and the only other duplicate registrations I see are more-specifics for ASNs which were assigned in blocks, 1381 and 3933, for example, but this doesn't seem to be such a case. Intel Corporation (ASN-INTEL) 99 University of Maryland (ASN-00) 99 Advanced Networks & Services Inc. (ASN-ANSBB-ASNNET-2-ASNBLOCK) 1381 Merit Computer Network Incorporated (ASN-NSFNETTEST46) 1381 NorthWestNet (ASN-NWNET-ASBLK1-ASNBLOCK) 3933 Oregon Department of Education (ASN-OPEN-NORTH) 3933 -Bill ________________________________________________________________________________ bill woodcock woody(a)zocalo.net woody(a)applelink.apple.com user(a)host.domain.com

Or is Microsoft gonna >cause the IP address space to expire sooner than we had planned? You're missing something. On the DNS issue, I would agree with you that their implementation has some serious shortcomings. On the other issue, I think there's something wrong with your customers. I have a computer on my home network running Windows NT 4. It's not a /24 network, it's a /29, and NT4 accepts a .248 netmask without any problem. -- William S.
