Re: what's a valid domain name?
From RFC 1123 One aspect of host name syntax is hereby changed: the restriction on the first character is relaxed to allow either a letter or a digit. Host software MUST support this more liberal syntax. p...@mail.nsbeta.info writes: Joseph S D Yao writes: The labels must follow the rules for ARPANET host names. They must start with a letter, end with a letter or digit, and have as interior characters only letters, digits, and hyphen. There are also some restrictions on the length. Labels must be 63 characters or less. A label must start with a letter? oh I don't think so. How about these domains which all have huge DNS traffic? 163.com 126.com 51.com 56.com yes 163.com is a domain name but 163 also can be treated as a label for domain com., is it? Thanks.

ddns and subdomains
Hi folks, I have ddns setup in a testing env, its working. ddns-domainname is dhcp6.example.com. Clients get assigned host.dhcp6.example.com My question is, is it correct to create a separate subdomain zone specifically for dhcp6.example.com so example.com zone itself doesn't have to be updated, and if so, how would example.com zone have to be configured to point to zone dhcp6.example.com?

No, BIND 8 was broken this was also. This was fixed in BIND 9. As for non-BIND name servers, anything goes.

Re: ddns and subdomains
There's nothing wrong with doing that. You would create delegation NS records in the example.com zone: dhcp6 NS some.name.server. dhcp6 NS other.name.server. You can of course use the same set of name servers as are authoritative for example.com.

At one point they were allowed, I believe ? What is the latest official RFC ? I don't think they've every been allowed. Why would you need to do this, instead of just using another level of subdomain? To get a literal period into a label, you need to escape it, e.g. foo\.bar.company.com instead of foo.bar.company.com. The latter is allowed, always has been, and is quite common. -- Barry Margolin, bar...@alum.mit.edu Arlington, MA *** PLEASE don't copy me on replies, I'll read them in the group *** ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users

What is the latest official RFC ? Periods, or dots, act as dividers in a domain name, separating the various labels. You may have a 'dotted host' in any zone you control. For example, if you control example.com, then some.host.example.com is a valid record name within that zone, as long as host.example.com is not delegated as a subzone.
