I'm running Bind 9.6 and dnsextd (llq and tsig handling). I have split DNS views based on source ip address and possession of a tsig key: internal-trusted/external-trusted/internal-visitor/external-visitor. The DNS server and clients are all mac 10.6+ so I'm taking advantage of mDNSResponder features such as looking in the system keychain for the tsig keys. I have a WAB subdomain for dns-sd, etc. I've had to replace dnsextd with an older version, since current macosx versions are dead. I wondered if the limited access to DNS records at the top level of my domain would be a problem. My first thought was to take over the DNS for this domain but rfc882 saying a domain must have at least 2 nameservers rules that out. Frankly, I probably don't understand enough about how glue records function...

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...

This seems to go right back to RFC 882 (November 1983): | The domain must provide redundant (i.e., two or more) name servers | to provide the name to address resolution service. These name | servers must be accessible from outside the domain (as well as | inside) and must resolve names for at least all the hosts in the | domain. RFC 1035 (November 1987) just mentions this in section 2.1 "Overview": | Different parts of the domain space are stored in different name | servers, although a particular data item will be stored redundantly | in two or more name servers. while RFC 2182 (July 1997), which I suspect is the one Anand had in mind, says in section 5 "How many secondaries?": | The DNS specification and domain name registration rules require at | least two servers for every zone. before going on to recommend more than two in most cases. -- Chris Thompson Email: c...@cam.ac.uk ___ 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
.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
