.TLD minimum number of nameservers rule
Sorry if this is slightly off-topic I've just discovered that the TLD where I've registered my domain requires a minimum of 2 nameservers for any subdomain, which is very sensible but I happen to have a special case on my hands. So I'd like to register a new domain elsewhere where they will allow a single nameserver execpt... I cant seem to find out what the rules are for other TLDs. *before* registering. Some kindly advise would be most welcome. ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

I suspect that most, if not all registries will require you to provide at least 2 name servers, because this is highly recommended in one of the RFCs (forget which one now). It will be quite unusual to find a TLD which allows just one name server for a delegation. If your special domain doesn't need to be under a TLD, then you can create your own delegation for it in a domain you control, with just one name server if you like.

RE: .TLD minimum number of nameservers rule
Or you could simply put a virtual IP address on the same name server (and any NATting required) and put it in as your second at the registrar. That is to say the Registrar would see the same name server with two different names and IPs so wouldn't know it was the same name server. -Original Message- From: bind-users-bounces+jlightner=water@lists.isc.org [mailto:bind-users-bounces+jlightner=water@lists.isc.org] On Behalf Of Anand Buddhdev Sent: Monday, December 12, 2011 9:32 AM To: nudge...@fastmail.fm Cc: bind-us...@isc.org Subject: Re: .TLD minimum number of nameservers rule On 12/12/2011 15:19, nudge...@fastmail.fm wrote: > Sorry if this is slightly off-topic > > I've just discovered that the TLD where I've registered my domain requires a > minimum of 2 nameservers > for any subdomain, which is very sensible but I happen to have a special case > on my hands. > So I'd like to register a new domain elsewhere where they will allow a single > nameserver execpt... > I cant seem to find out what the rules are for other TLDs. *before* > registering. > Some kindly advise would be most welcome.

Fwd: Re: .TLD minimum number of nameservers rule
Thanks all. Chris, Anand that's very useful to know, sorry Jeff and Philippe, your interesting suggestions wont work in this case. If I attack the problem from the other way down instead, the fact my current registra doesn't allow me to add PTR or DNAME records to my top level domain limits what exactly ? For instance, would this be a problem when implementing a wide area bonjour subdomain using my own local dns server for clients that are mobile (internal/external) ? I'm only allowed to add A NS MX CNAME TXT and SRV records via the web interface of my registra and I imagined that I'd need PTRs or a DNAME or some ther glue frustratingly unavailable. Having heard your response to my original question, I'm now desperately wishing that I got that wrong...

What IS the problem, exactly? You're describing two things that doesn't seem to be related: number of NS for a zone, and PTR/DNAME records. If you don't "own" an IP address, then usually you don't need to bother about PTR records at all. If you need to change PTR record for an IP address that you use (e.g. VPS, colo, home connection, etc) you usually need to ask your ISP to update/change it. DNAME creates an alias for one or more subdomains of a domain. Chances are you won't need it for common uses. > For instance, would this be a problem when implementing a > wide area bonjour subdomain using my own local dns server for clients that are > mobile (internal/external) ? Bonjour should work even without a DNS server. > > I'm only allowed to add A NS MX CNAME TXT and SRV records via the web > interface ... because those are the ones mostly used. > of my registra and I imagined that I'd need PTRs or a DNAME or some ther glue > frustratingly unavailable.

You could always create your own DNS server if you REALLY need those record types :) The cheapest VPS is about $15/year, which should be more than enough for a secondary DNS server. -- Fajar ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
