Discussing a 'you don't handle long names' issue that I discovered with an application's developer, I thought I'd create a test case or two for him.
I did, but they don't resolve. I might be missing something, so some other eyes would be appreciated. The test domain is hosted on godaddy's DNS. (Because, well, it's a test domain.) dns fingerprint (w3dt.net) claims their server is 'VeriSign ATLAS' Does anyone have experience with this server? The recursive servers queried are mine (bind) - I've flushed their caches. I've also tried several web services that run DNS lookups; the results are consistent. NXDOMAIN The two names in question each have AAAA records: oh.what.a.beautiful.morning.oh.what.a.beautiful.day.oh.what.a.wonderful.feeling.everythings.lost.in.the.hay.litts.us oh-what-a-beautiful-morning.oh-what-a-beautiful-day.oh-what-a-wonderful-feeling.everythings-lost-in-the-hay.litts.us The current zone serial number is 2015031503 dig reports that serial with a NXDOMAIN response to each name, so it's not a propagation issue. Exporting the zone file (yes, this is the entire file -- 10 records) gives: ; SOA Record LITTS.US. 3600 IN SOA ns71.domaincontrol.com. dns.jomax.net ( 2015031503 28800 7200 604800 3600 ) ; A Records @ 3600 IN A 97.74.42.79 ; CNAME Records www 3600 IN CNAME @ ; MX Records @ 3600 IN MX 10 nano.litts.net ; TXT Records @ 3600 IN TXT "v=spf1 ip4:96.233.62.58 ip4:96.233.62.59 ip4:96.233.62.60 ip4:96.233.62.61 ip4:96.233.62.62 mx a:micro.litts.net a:nano.litts.net a:pico.sb.litts.net a:overkill.sb.litts.net a:hagrid.sb.litts.net a:smtp.litts.net -all" ; AAAA Records oh.what.a.beautiful.morning.oh.what.a.beautiful.day.oh.what.a.wonderful.feeling.everythings.lost.in.the.hay 1800 IN AAAA 2001:4830:11a2:941::43 beautiful.feeling 600 IN AAAA 2001:4830:11a2:941::43 oh-what-a-beautiful-morning.oh-what-a-beautiful-day.oh-what-a-wonderful-feeling.everythings-lost-in-the-hay 600 IN AAAA 2001:4830:11a2:941::43 ; NS Records @ 3600 IN NS ns71.domaincontrol.com @ 3600 IN NS ns72.domaincontrol.com Dig lookups fail on the long names, but the SOA shows the correct serial. dig oh.what.a.beautiful.morning.oh.what.a.beautiful.day.oh.what.a.wonderful.feeling.everythings.lost.in.the.hay.litts.us aaaa ; <<>> DiG 9.9.4-P1 <<>> oh.what.a.beautiful.morning.oh.what.a.beautiful.day.oh.what.a.wonderful.feeling.everythings.lost.in.the.hay.litts.us aaaa ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 57860 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 1 ;; OPT PSEUDOSECTION: ; EDNS: version: 0, flags:; udp: 4096 ;; QUESTION SECTION: ;oh.what.a.beautiful.morning.oh.what.a.beautiful.day.oh.what.a.wonderful.feeling.everythings.lost.in.the.hay.litts.us.
