RE: IP Addresses for colocation
by Cutler, James R 22 Jun '01

Mark, I would like to understand why you need to use access by IP address rather than DNS name. Using DNS CNAME records for URL domain lookup would seem to insulate one rather well from renumbering.

Is there a better way to get a /24 that can "go anywhere"? Or should I just justify a /24 at the colocation facility and go through the same process should we decide to change? Is there a way to buy a routable /24? Thanks in advance for any advice, on or off list.

RE: IP Addresses for collocation
by Hire, Ejay 22 Jun '01

Yes and no. Can you half-drown yourself at the watering hole? If you (BGP) peer with the ISP(s) at the Colo facility, then you can advertise your Ip space and it will work at any facility. The bad news is that if you advertised Provider A's Ip space, and then go to a colo not served by Provider A, they will (rightly) want their Ip's back. If your Ip requirements were large enough to justify "Provider independent" space, then it would be portable everywhere. Good Luck, Ejay -----Original Message----- From: Mark J.

Deaggregation of class B..
by Bleetzin Boopzin 21 Jun '01

21 Jun '01

Can anyone offer some advice on how to explain to my boss that further deaggregating and spreading little announcements of our class B to different ISPs all over the world is a bad idea? Are there any specific web page references or previous NANOG posts that accurately explain the risks/implications from an objective viewpoint? -- Thanks __________________________________________________ Do You Yahoo!?

ARIN to Allocate from 67.0.0.0/8 and 68.0.0.0/8
by Richard Jimmerson 21 Jun '01

21 Jun '01

In the near future, ARIN will begin making allocations from 67.0.0.0/8 and 68.0.0.0/8. This will include allocations of /20 and shorter prefixes, according to ARIN's minimum allocation policy. For informational purposes, a list of ARIN's currently administered blocks can be found at http://www.arin.net/regserv/IPStats.html Regards, Richard Jimmerson Director of Operations American Registry for Internet Numbers (ARIN)

Hmm, that shouldn't come as a surprise since it isn't even listed as an MX: [andy@home:mail andy]$ dnsmx aol.com 15 mailin-01.mx.aol.com 15 mailin-02.mx.aol.com 15 mailin-03.mx.aol.com 15 mailin-04.mx.aol.com In addition, unless you have some special routes, I'm not even sure how you are getting anywhere with that name: [andy@home:mail andy]$ dnsip air-yh04.mail.aol.com 172.18.147.41 Which is clearly a private class address as defined by RFC 1918. Probably a big no-no publishing private addresses in your public DNS, but this is AOL we're talking about, right? :-) Andy -- [-----------[system uptime]--------------------------------------------] 6:40pm up 42 days, 21:18, 4 users, load average: 1.14, 1.29, 1.20

aol rejects mailing lists?
by Christian Kuhtz 20 Jun '01

20 Jun '01

Hey guys, I've noticed on one of the mailing lists that I'm running that AOL has just started bouncing email (like literally a few minutes ago) sent to subscribers of the list. Email does get delivered properly when sent directly to the subscribers. If the mail gets delivered thru the list, it's rejected with a 550 MAILBOX NOT FOUND which is bogus. Anyone encountered this before? How do I get them to stop this nonsense? Help?
