Yes, yes, you're all entirely correct about that. Back in the day, they were all the same, but this hasn't been true in quite some time. I'd be happy if they took out full-page adverts in the New York Times, as long as they let us know about these things. Of course, one could say that it's too little, too late . . . ----------------------------------------------------------- Roland Dobbins <rdobbins(a)netmore.net> // 818.535.5024 voice -----Original Message----- From: Sean Donelan [mailto:sean@donelan.com] Sent: Tuesday, September 19, 2000 7:59 PM To: nanog(a)merit.edu Subject: RE: Root zone change -- d.gtld-servers.net On Tue, 19 September 2000, Randy Bush wrote: > > In this particular case, I can see where information about root nameserver > > changes might be of use in figuring out broken name resolution due to > > caching issues, etc. > > indeed! but these date are not about root nameservers. I believe Randy operates/provides the servers for more TLDs in the root zone than any organization in the world, so I can understand why he is being pedantic about the root zone file. NSI is not changing the name servers for "." (root) NSI is changing the name servers for some TLDs. If you changed the name servers for .CA or .US, would those operators send out a notice or just do it. Since NSI has experienced at least one problem making this change in the past, which caused a lot of traffic on NANOG; I think its commendable they are now providing advance notice. If it will become a regular feature, NSI may want to provide a pointer to a different place where NSI will continue to provide the same information in the future instead of posting it on NANOG.

RE: DNS Updates
by Karyn Ulriksen 20 Sep '00

Ben, There is no major list for when DNS servers update. Basically, it works like this.... Part of your DNS records has information on how long to store information on a DNS server once it is gathered. The remote DNS server (ie, Earthlink's) takes the information as a "recommendation". Most DNS servers will go by this recommendation. However, there are quite a few DNS servers out there that will ignore the recommendation. Generally, the servers that disregard the recommended time will update with new information only after a time configured by their administrator. In most cases, this will be about 24-48 hours. However, some ISPs may lengthen these times for whatever reason or possibly due to misconfiguration. If you are not seeing updates as quickly as you'd like, have your ISP set the information in the SOA portion of your DNS record to be short lived. If the current information is set to 30 days, some DNS servers may not see your new information until after 30 days and there may be little you can do about the current state. Ask your current DNS provider to set your TTLs for your domain to 24-48 hours to alleviate this type of problem in the future. If they don't know how to do this, you may want to arrange for a new DNS provider. --------------------------------------------------------------------- Best regards, Karyn Ulriksen Director of Network Operations PublicHost, A SiteStream Company 22 Mauchly, Suite 200 Irvine, California 92618 USA Phone: (949) 743-2000 email: kulriksen(a)publichost.com URL: http://www.publichost.com <http://www.publichost.com/> =========================================== -----Original Message----- From: Benjamin Harper [mailto:harperb@hotmail.com] Sent: Wednesday, September 20, 2000 3:06 PM To: nanog(a)merit.edu Subject: DNS Updates Hi Everyone, I was wondering if anybody knew when most DNS servers update their records with regard to changes in DNS hosts for a domain.

Yes, in the common parlance, they're referred to as the 'root' servers.

> Just because once upon a time the root nameservers and the most common > Top-Level-Domain nameservers were one in the same doesn't mean you can > freely refer to the TLD servers as "root" servers! You might want to check your RFC's. There's root servers and TLD root-servers, not to mention ccTLD root servers. Also, if you're running public registration at the SLD level (like UK is), you also have SLD root servers. Randy is technically correct, it was a notice about TLD root servers. However, this does not invalidate its operational importance. On DOMAIN-POLICY we have been taking NSI to task for making unannounced changes to the core structure. Albeit, mostly changes to whois (which some of y'all have complained about). I agree that NSI posting this notice on NANOG is a GoodThing(tm). Would you rather a tad too much notice, or none at all? <sheesh>.

Well, this is the *North American* list, after all. Nobody's 'falling' for anything. It's just that since they seem to be willing to actually -tell- us about something before they do it, we ought to encourage that trend, even though it's a good decade or more late in coming. The .com and .net domains are certainly where the most money gets spent online, I should think. It may not be politically-correct to say so, but those are the domains that still matter the most to the vast majority of users and vendors. Last time I checked, it was dedicated people at .com and .net and .org domains - people like yourself - who've done the lion's share of both the technical and organizational work which makes the whole thing function. This is changing, of course, but excepting Tim Berners-Lee and a few others, I think it still holds true today. It'll be interesting to see what comes of the whole .us discussions currently being held. ----------------------------------------------------------- Roland Dobbins <rdobbins(a)netmore.net> // 818.535.5024 voice -----Original Message----- From: Randy Bush [mailto:randy@psg.com] Sent: Tuesday, September 19, 2000 7:57 PM To: woods(a)weird.com Cc: nanog(a)merit.edu Subject: RE: Root zone change -- d.gtld-servers.net [ not disagreeing greg, just using your post as a soapbox ] > Just because once upon a time the root nameservers and the most common > Top-Level-Domain nameservers were one in the same doesn't mean you can > freely refer to the TLD servers as "root" servers! \\\ a handful out of hundreds of should iana post to this list every time they change servers for TZ, KE, UG, CA, MX, ...? it would be easy to do if people are really interested in this stuff at that level of detail. it is quite likely that french operators care a lot more about FR than COM. and remember that canada, mexico, and other places think that they're part of north america. though i suspect they may wistfully regret having a bully in the neighborhood. and let's not forget to cover servers for the extremely popular sites, e.g. aol.com, nasa.gov, ... it is amusing that members of this list, who so often spend inordinate amounts of time railing against nsi, fall so simply for their "we have the most important zones" marketing. then again, i am repeatedly told by my european, alyc, african, ap, ... friends that the whole domain name noise is an american problem/disease and we should shut up and use the US tld. interesting that nsi could be on the grab for that one too. randy
