Re: CNAME only zone?
If CloudFlare is similar to Akamai's solution, recursive servers never see the CNAME record. Instead, when the auth server receives the query for the A record of the apex, it performs its own query for the CNAME, and returns the result of this. In other words, if your theory is correct, this CNAME is window dressing for the customer (yes, they gave me a CNAME, I'm happy!) while actually they serve A records that they've specified to give the same answer as whatever address the A record of such-and-such name has. What they present in their customer interface or store in their zone-file-equivalent is arbitrary. Makes DNSSEC interesting. It's always helpful to be able to tell your customer yes, we gave you a CNAME, just like you asked for. We do it even if our competitors say no! John Wobus P.S. Hm, I wonder if a TLD will give me a three part CNAME: if they've given me example.com. CNAME foo, will they also give me www.example.com.

CNAME only zone?
Is it possible to create a zone file that only contains a CNAME? The request I got is to create a CNAME to point shop4water.com to shop4water.hostedbywebtstore.com. We own shop4water.com – hostedbywebstore.com is something external that we don’t own. I’ve reviewed past posts and searched the internet. I see things saying “you can’t have CNAME only” or “you can” or “you should use DNAME instead” and then others saying that “you can’t use CNAME or DNAME with any other record and the SOA itself is a record”. So my basic question is: Is it possible to do this? If so what should the zone file for shop4water.com look like? Is there another way to make queries for shop4water.com go to shop4water.hostedbywebtstore.com?

The records at the apex of the zone are those with the same name as the zone - normally the SOA, NS, MX, and other records.

Re: CNAME only zone?
I don't know what you mean by that. Apex of what exactly - my zone file? Can you tell me exactly what the zone file should look like with the CNAME record at the apex? Determine the address(es) for the target domain name shop4water.hostedbywebtstore.com (I'm using 127.0.0.1 as an example), and add each to an A record in the zone, which should look a bit like this: $TTL 3600 @ IN SOA shop4water.com. root.shop4water.com. ( 1 ; serial 3H ; refresh 1H ; retry 1W ; expiry 1H ); negTTL IN NS ns7.worldnic.com. IN NS ns8.worldnic.com. IN A 127.0.0.1 ; replace w/ IP of target As Phill said, a CNAME instead of the A record is illegal at the apex (i.e. the top) of the zone; CNAME must not exist with other data e.g. NS or SOA records, which are mandatory for a zone.

Care to enlighten me as to what those workarounds would be? Not knowing the exact situation puts me at a distinct handicap in trying to do so, but I can suggest some possibilities beyond what was suggested by Jan-Piet and Phil. - A cron job to look up the desired name and nsupdate(8) the A record for shop4water.com. when that address changes - HTTP redirects, or just a redirect for shop4water.com to point to your desired CNAME target; www.shop4water.com *can* be a CNAME. - Find different hosting. Also - why is it a registrar can do a CNAME only but we mere mortals can't? Only approved registrars are allowed to update records in official top-level domains. You can make as many CNAME records as you like, playing by the rule that a CNAME cannot coexist with a record of the same name and any other RRtype. Registrars are also bound by the reality of DNS. If you want a CNAME, they do not delegate the zone to you. They remove any NS records which had been in place for your zone, and your nameservers are no longer in use for that name. In fact by not being delegated, it ceases to be a zone. In fact documentation from Amazon (it is apparently their web store I've since learned) suggests doing it at registrar so I'll probably go that route but I'm wondering why it should work there but not on one of my delegated name servers. Phil answered this, but to restate/repeat, a delegated zone *must* have SOA and NS records at the zone apex. Meaning: if shop4water.com is delegated, the parent com zone at a a minimum has NS records for shop4water.com, and your zone *must* contain SOA and NS records for shop4water.com. Those SOA and NS violate the rule that a CNAME cannot coexist with a record of the same name and any other RRtype. -- Offlist mail to this address is discarded unless /dev/rob0 or not-spam is in Subject: header ___ 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
RE: CNAME only zone?
Also note that other workarounds will solve the same problem in a better way. Care to enlighten me as to what those workarounds would be? If all the use cases for the CNAME are for http traffic, just configure an http server/load balancer/etc. under your control to return a 302 or 301 redirect back to the client browser and you maintain control if needs change in the future. 1. Point DNS A record for shop4water.com to an IP of a webserver under your control... 2. Use insert your favorite webserver here (using URL Rewrite rules, perl, etc.) to send a redirect back to the browser to direct them to the shop4water.hostedbywebstore.com URL. Depending on whether you want to preserve the URL or not can vary the type of redirects that you will be configuring but that is fairly simple to setup on a variety of well known http servers.
