Delay in domain name recognition

[mmckenna]

Hi all,

I'm just wondering if there is a way to reduce the time between creating a site in an ISPConfig server and for it to be recognised as a valid address on a client machine. I am using a local host server which is running nginx. At present I have to restart bind on my server and flush my DNS on a client machine in order to get the site recognised.

Thanks in advance,
M.

The bind restart is not required as bind is restarted / reloaded automatically when the domain gets created in dns. The issue is caused by the dns cache on your client machine or by a caching dns server which is used by your client computer to resolve names. A dns record has a field "ttl" which sets the time that caching servers hold a domain name in its cache vbefore they query your master dns server again. So if you set ttl to a smaller number, the changes will get recognized faster.

Thanks Till, I'll have a look at reducing the ttl, makes sense.
