I have an mpwt.gov.la domain hosted on OVH but managed by the lao government. I added an A record to the DNS table of ns101.ovh.net for a public IP I own:

Domain: iram.mpwt.gov.la
TTL: 0
Type: A
Target: 202.xxx.xxx.xxx

After 5 days, I still have ERR_Name_not_resolved in my browser, and when I'm checking for propagation with https://www.whatsmydns.net/ nothing is happening, every name server returns "unknown".

Are government domain names managed differently than others and sub-domain cannot be added through the host?

  • Should be the same. What happens when you dig app.example.gov.la @<your domain's registered DNS servers>? – Paul Calabro Jan 18 '16 at 8:56

    Why is there a TTL with 0 value ? – Dom Jan 18 '16 at 9:03

    This question will be a lot easier to help with if you tell us the actual fully-qualified domain name in question. – MadHatter Jan 18 '16 at 9:03
  • What DNS server did you add that record to? – duskwuff -inactive- Jan 19 '16 at 5:29
  • I added real info. @Paul Calabro is the command dig iram.mpwt.gov.la@ns101.ovh.net ? – syldor Jan 19 '16 at 6:58

This being a 'government domain name' is not a factor. It works just like other domains.

The mpwt.gov.la zone is not delegated to ns101.ovh.net but rather as seen below:

mpwt.gov.la.            3600    IN      NS      ns2.lanic.gov.la.
mpwt.gov.la.            3600    IN      NS      ns3.lanic.gov.la.
mpwt.gov.la.            3600    IN      NS      ns1.lanic.gov.la.
ns1.lanic.gov.la.       3600    IN      A
ns2.lanic.gov.la.       3600    IN      A
ns3.lanic.gov.la.       3600    IN      A

(See dig +trace +add iram.mpwt.gov.la)

Ie, while you have created a zone with the same name (mpwt.gov.la) and added an address record for iram.mpwt.gov.la at the nameserver ns101.ovh.net, no one will be querying ns101.ovh.net as the domain is delegated elsewhere.
It is, however, possible to get this record back if you explicitly query ns101.ovh.net directly (see dig @ns101.ovh.net iram.mpwt.gov.la +norec).

Unless the domain name owner is going to delegate this to your specified nameserver(s), you should probably ask them to add the record to their zone instead.
