Hi, Een interessante discussie op /. http://ask.slashdot.org/article.pl?sid=05/04/18/198259&tid=95&tid=128&tid=4 cluge asks: "It seems that several large providers give their users DNS servers that simply ignore DNS time to live (TTL). Over the past decade I've seen this from time to time. Recently it seems to be a pandemic, affecting very large cable/broadband and dial up networks. Performing a few tests against our broadband cable provider has shown that only one of the three provided DNS servers picked up a change in seven days or less. After turning in a trouble ticket with that provider - two of the three provided DNS servers were responding correct - while the third was still providing bad information more than two weeks after that specific change. What DNS caches ignore TTL by default? Is there a valid technical reason to ignore TTL?" -- Sabri Berisha, - CCNA, JNCIA #747 Internetworking Professional - +31 (0) 6 19890416 http://www.cluecentral.net - http://www.virt-ix.net
