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').

RE: 96.0.0.0/6 reachability testing
But for the sanity and comfort of other list users, would it be too much to ask that people with annoying tacked-on .sig's use a personal mail account when posting to the list? I hear Google offers nice email accounts for a reasonable price. That often results in people sending html instead of a legal sig. People who filter on such sigs are likely to filter on html too. People who don't filter on sigs do filter on html. Choose your evils carefully. brandon

What follows is an off-topic meta-comment, so if you weren't following earlier stuff in this thread, you might as well stop reading. My apologies for furthering this.

While he could spend a huge amount of time trying to explain to someone at Time Warner that it is a stupid thing to do, I sure he has better things to do... I don't see anywhere in the NANOG charter that says we have to use our corporate email addresses in correspondence with list. From what I've seen, most of us don't. I agree 100% that trying to get $corporation to remove the useless and annoying .sig's is like tilting at windmills. But for the sanity and comfort of other list users, would it be too much to ask that people with annoying tacked-on .sig's use a personal mail account when posting to the list? I hear Google offers nice email accounts for a reasonable price. At the risk of hypocracy as well as off-topicness, I'm rather hoping people don't follow this advice. There are a few well-known people on this list whose employment situations and other affiliations don't need much explanation for anybody who has been following the industry closely. There are many more NANOG posters who aren't so well known. Some of these people post to the list a lot, often making assertions without evidence to back them up, and without enough information about who the poster is to figure out whether they're speaking from inside knowledge or relevant experience, whether they work for somebody with a strong stake in the issue under discussion, or or whether they are most likely just making stuff up. I'd much rather see messages with .signatures full of legalese at the end (generally after I've stopped reading anyway), than messages sent with less information about the poster's identity. I realize I'm following my own advice here, largely due not having changed my mailing list configurations after a period of unstable employment a few years ago. -Steve Gibbard Network Architect Packet Clearing House www.pch.net Speaking for myself, not for my employer, and not for any NANOG-related committees I've been on in the past.
