Hi *, in august IANA handed 77/8 78/8 79/8 to RIPE which started handing out those ranges 2 months ago. We (Telefonica Deutschland AS6805) are seeing a lot of reachability problems most likely caused by not updated bogon filters. For testing purposes 77.181.114.4 aka bogon.mediaways.net is up for icmp/http. Please check and possibly update your filters. Flo (aka flo(a)telefonica.de) -- Florian Lohoff flo(a)rfc822.org +49-171-2280134 Heisenberg may have been here.

They're very good at passing cert tests.) Many don't want to know about UNIX and Open Source Software. I don't mean not use it in production, but don't want to know anything about it at all. They don't want to know how the internals of any of it works. They want to design by book regurgitation and operate by point-and-click. They don't think about things organically or as the Big Picture, rather they have a very narrow point of view. It's a change of personality type behind this. Do the least amount of work for the most amount of money. It's not geek-excitement that drives them.

Back in the old days, say 10 years ago, you could run a network by the seat of your pants using rules of thumb about interpretation of in-addr.arpa records. And you could be quite successful at running a network using such techniques because everybody else was doing pretty much the same thing. Because of this uniformity, you could make a lot of intelligent guesses and resolve problems. However, I think times have changed, there is no longer uniformity among the people making technical decisions about Internet networks and many rules of thumb don't work any more even though they are still out there in network operator folklore. In fact, most people making network architectural decisions about Internet networks don't participate in NANOG any more. Most people making network operational decisions also do not participate in NANOG anymore. It's not just that many people have left NANOG behind, but a lot of newcomers to the industry over the past few years have not joined NANOG because they don't get why it is relevant to them. Not that I'm complaining about the message quoted above. It is a great example of the useful information that one can find in this mailing list. I wish there were more messages like this one, i.e. people sharing info rather than complaints and pleas for help. --Michael Dillon

Back in the old days, say 10 years ago, you could run a network by the seat of your pants using rules of thumb about interpretation of in-addr.arpa records. And you could be quite successful at running a network using such techniques because everybody else was doing pretty much the same thing. Because of this uniformity, you could make a lot of intelligent guesses and resolve problems. However, I think times have changed, there is no longer uniformity among the people making technical decisions about Internet networks and many rules of thumb don't work any more even though they are still out there in network operator folklore. In fact, most people making network architectural decisions about Internet networks don't participate in NANOG any more. Most people making network operational decisions also do not participate in NANOG anymore. It's not just that many people have left NANOG behind, but a lot of newcomers to the industry over the past few years have not joined NANOG because they don't get why it is relevant to them. Not that I'm complaining about the message quoted above. It is a great example of the useful information that one can find in this mailing list. I wish there were more messages like this one, i.e. people sharing info rather than complaints and pleas for help. --Michael Dillon
