DNS is partially broken again

[BailOut]

YarisBueller,

It appears that the same DNS issues we touched on early in 2008 have reappeared. DNS requests for yarisworld.com get a response but www.yarisworld.com does not.

The WHOIS record shows that DNS for yarisworld.com should be served by:

Domain servers in listed order:
NS1.YARISWORLD.COM
NS2.YARISWORLD.COM

But neither of those servers exist in the master DNS records:

~$ dig any ns1.yarisworld.com

; <<>> DiG 9.4.2-P2 <<>> any ns1.yarisworld.com
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 25507
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;ns1.yarisworld.com. IN ANY

;; Query time: 0 msec
;; SERVER: 10.2.1.2#53(10.2.1.2)
;; WHEN: Thu Jan 1 08:42:28 2009

~$ dig any ns2.yarisworld.com

; <<>> DiG 9.4.2-P2 <<>> any ns2.yarisworld.com
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 54765
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:

;; SERVER: 10.2.1.2#53(10.2.1.2)
;; WHEN: Thu Jan 1 08:38:13 2009
;; MSG SIZE rcvd: 36

However, there are generic NS records in the DNS record held by the registrar, GoDaddy, which point to ns*.ds.nac.net:

~$ dig any yarisworld.com

; <<>> DiG 9.4.2-P2 <<>> any yarisworld.com
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 39729
;; flags: qr rd ra; QUERY: 1, ANSWER: 3, AUTHORITY: 2, ADDITIONAL: 0

;; QUESTION SECTION:
;yarisworld.com. IN ANY

;; ANSWER SECTION:
yarisworld.com. 13937 IN A 209.123.181.71
yarisworld.com. 13937 IN NS ns2.ds.nac.net.
yarisworld.com. 13937 IN NS ns1.ds.nac.net.

;; AUTHORITY SECTION:
yarisworld.com. 13937 IN NS ns1.ds.nac.net.
yarisworld.com. 13937 IN NS ns2.ds.nac.net.

;; Query time: 0 msec
;; SERVER: 10.2.1.2#53(10.2.1.2)
;; WHEN: Thu Jan 1 08:44:23 2009
;; MSG SIZE rcvd: 122

So let's see what NAC (the spammer and malware-writer friendly hosting service that you mentioned you were going to get away from last year) has for yarisworld.com:

~$ dig @ns1.ds.nac.net any yarisworld.com
dig: couldn't get address for 'ns1.ds.nac.net': not found

Uh oh, nobody's home. Let's try the other one:

~$ dig @ns2.ds.nac.net any yarisworld.com
dig: couldn't get address for 'ns2.ds.nac.net': not found

And therein lies the problem. "yarisworld.com" works because there is an A record for it at GoDaddy, but "www.yarisworld.com" does not because the server(s) hosting the core record do not have a CNAME (alias) entry for www, nor do the supposed tertiary servers respond at all (so even if they had CNAME entries it would not matter).

This issue is simple to resolve. Please simply create a CNAME pointing "www" to "yarisworld.com" right alongside the existing A record at GoDaddy.

$ dig www.yarisworld.com

; <<>> DiG 9.4.2-P2 <<>> www.yarisworld.com
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 56063
;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 2, ADDITIONAL: 0

;; QUESTION SECTION:
;www.yarisworld.com. IN A

;; ANSWER SECTION:
www.yarisworld.com. 6320 IN CNAME yarisworld.com.
yarisworld.com. 6320 IN A 209.123.181.71

Thanks for fixing that.
