Aggregation Summary
The algorithm used in this report proposes aggregation only
when there is a precise match using the AS path, so as
to preserve traffic transit policies. Aggregation is also
proposed across non-advertised address space ('holes').

ARIN's RESTful Whois Directory Service Available 26 June
- Forwarded message from Member Services - From: Member Services Date: Thu, 24 Jun 2010 13:00:42 -0400 To: "arin-annou...@arin.net" Subject: [arin-announce] ARIN's RESTful Whois Directory Service Available 26 June ARIN is deploying an improved Whois service called Whois-RWS on 26 June 2010. Included in the deployment are the following services that provide the general public with access to ARIN's registration data. * a RESTful Web Service (RWS) * a NICNAME/WHOIS port 43 service * a user-friendly web site (http://whois.arin.net) When using Whois-RWS you will notice some differences in behavior for certain queries and corresponding result sets on the NICNAME/WHOIS TCP port 43 service. These minor differences are documented at: https://www.arin.net/resources/whoisrws/whois_diff.html ARIN's Directory Service for registration data has used the NICNAME/WHOIS protocol since its inception. The limitations of the NICNAME/WHOIS protocol are well known and documented in RFC3912. Whois-RWS was created as an alternative to the ARIN Whois and will provide much richer functionality and capability to the community. Whois-RWS can easily be integrated into command line scripts, or it can be used with a web browser, which makes it applicable for programmatic consumption and accessible for interactive use. ARIN will continue to maintain services for the NICNAME/WHOIS protocol on TCP/43. This is achieved by using a proxy service to translate traditional ARIN Whois queries into Whois-RWS queries. However, ARIN recommends use of the RESTful Web Service. Those who choose to use the Whois-RWS Proxy will find it has many features unavailable over the existing Whois service, including: * Support for new query types such as CIDR queries * Better feedback for ambiguous queries * More finely scoped record type queries * Options for NICNAME/WHOIS clients that re-interpret traditional parameters used by ARIN's service. * RESTful URL references, useful for embedding into documents and e-mail * Better grouping of record types and delineation of results Another major benefit is that data from ARIN's registration database is distributed to the Whois-RWS servers many times throughout the day, versus the once-a-day update of ARIN's previous Whois service. Changes will be reflected more quickly through Whois-RWS, so query results will be more current than the previous Whois service. ARIN continues to welcome community participation on the Whois-RWS mailing list, and we invite you to subscribe and provide feedback to: http://lists.arin.net/mailman/listinfo/arin-whoisrws Regards, Mark Kosters Chief Technical Officer American Registry for Internet Numbers (ARIN) - End forwarded message -

I can vouch for the fact that the batch of Juniper EX-PWR-930-AC modular power supplies shipped around June/July last summer had some quality issues. We've replaced about 10 so far (out of about 140) in the year we've had them. Presumably they've fixed this on new batches. It's a good thing we sprang for the redundant power supply modules in those switches. Compare this to the Nortel (now Avaya) BayStack 55xx line where we've had approximately 0 built-in power supply and maybe 2-3 unit failures for other reasons in the last 3 years.
Re: ATT BGP - Advertising my network on accident
Looks like the prefix in question is 208.91.48.0/22 and it was briefly announced by 7018 yesterday, but that announcement seems to be gone now. I see 11734 is announcing 208.91.48.0/22 + 208.91.48.0/24 now, but not 208.91.49.0/24 - 208.91.51.0/24.

I wonder how much of the de-aggregation in the routing table is attributable to issues like this?
