Clearly, all of them can be described as "leaf" ASes. None of them seem to have multihoming customers (or at least not THAT many). I seem to remember a person from Covad saying that their deaggregation was going to be temporary (http://www.merit.edu/mail.archives/nanog/2004-11/msg00366.html) for some value of temporary, but what about the others? Any of the rest of you want to speak up and explain this? ===== David Barak -fully RFC 1925 compliant- __________________________________ Do you Yahoo!? Yahoo! Mail - now with 250MB free storage.

RE: identifying application type of network traffic

I believe NBAR stats are accessible via SNMP, so you can use MRTG to graph application utilization. http://vermeer.org/display_doc.php?doc_id=6 ___________________________________________________________________ Thanks, Rick Cheung -----Original Message----- From: owner-nanog(a)merit.edu [mailto:owner-nanog@merit.edu]On Behalf Of Adam Atkinson Sent: Thursday, December 16, 2004 11:17 AM To: NANGO Subject: RE: identifying application type of network traffic > Currently, I use (protocol, port_number) as indicator > of application.

RE: Interesting DNS problem.

That's called "hosting". There only thing "wrong" with it is they aren't split across two - which is generally recommended operationally. Did you customer say why they thought that was a problem i.e. "can't reach" "won't resolve" etc.? ARIN says you own that IP space so I'm not sure what you are trying to tell us...
