Faster Updates for DNS Root Servers Arrive
Tee Emm writes "VeriSign's DNS Rapid Update notice period (as announced on NANOG mailing list) expires today. Beginning September 9, 2004 the SOA records of the .com and .net zones will be updated every 5 minutes instead of twice a day. The format of the serial number is also changing from the current YYYYMMDDNN to a new one that depicts the UTC time." We first mentioned this back in July, but it's finally launching now.
as I understand it, this would allow for propogation of new domains to be completed faster. this is *theoretically* a good thing, but it means that applications cannot cache DNS as effectively for nonexistant domains. this may end up causing a *lot* heavier load on the root DNS servers. much as we'd all love that functionality (who doesn't want to see their new domain a few minutes after they buy it?), there was a reason why they designed it the way they did.
Now spammers can rotate through domains faster than ever before!!
Doesn't that mean they're updating every fifteen minutes, not every five?
Meep meep
on how many domains a spammer can register over time -- for much the same reason that you can still have huge bandwidth even if your latency is crap. It's just a question of reducing the initial delay from registration to activation.
HAND.
