BIND directly resolve the hostname to internet
Is there away to resolve the hostname after creating a new subdomain. So we don't need to wait internet need some times to able to resolve the hostname. For example, if I add new subdomain to "test.example.com", I can directly ping to this hostname from internet. Is it possible ?
Thanks a lot for your answer. |
Hi,
If you add a new subdomain, then you don't have to wait until the other name servers are updated. That is because the new record does not exist in their cache, so they have to query your dns that is authoritative for the domain in question. Regards |

Hi,
I've never used avahi, but from what I've read, it looks like its usage is limited inside a LAN. If you add a new host in your domain and you want it to be accessible from the internet, you should add a record for that host in the domain's authoritative dns server. Since this is a new host (or subdomain if you prefer), it doesn't exist in any other name server cache, so if someone wants to access the new host, he has to query the authoritative dns directly (or through his ISP dns) and get the right answer. This answer then remains in the querying name server cache, until the TTL expires (normally after 1 day), or until that dns is restarted. Regards |
