;; QUESTION SECTION: ;mumbai-m.site. IN NS ;; ANSWER SECTION: MUMBAI-M.site. 3380 IN NS win-1ikkrphg9jj. I seemed to have cached only one nameserver - which does not make operational sense - neither does the name I've cached. $ dig mumbai-m.site aaaa ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 1 ;; QUESTION SECTION: ;mumbai-m.site. IN AAAA ;; AUTHORITY SECTION: MUMBAI-M.SITE. 3473 IN SOA win-1ikkrphg9jj. hostmaster. 4 900 600 86400 3600 The Zone looks like its not set up properly.. the admin has added dots where they should not have... The "win" and Serial No. of "4" suggests to me that this is a windows machine, and as both nameservers are on the same IP, the adminstrator is in need of some DNS training.. As for your errors, I'd guess you may run IPv6 but this person doesn't appear to as asking for the Quad-A record returns the SOA (you got to the right place but there is no answer to your question) In summary - the administrator of MUMBAI-M.SITE has a broken zone configuration. Doing a "whois MUMBAI-M.SITE", seems they are hiding behind "whoisguard.com" to remain anonymous - which suggests they have something to hide. I don't get the vibe that this domain is owned by a child or someone who needs protection from the evilness of the Internet...
