How to flush DNS in Ubuntu 13.10?

Question

We recently moved our website to a new server. But after changing the NS (name server) records, I can't access my website. The hosting provider said we need to flush the DNS settings in order to see the new website.

I searched relating to this but I couldn't find a way to flush DNS settings in Ubuntu 13.10.

Usually NS takes time to update its records & it depends. As far as I know, Ubuntu doesn't cache DNS by default but your ISP (assuming). Refer How do I clear the DNS cache? — AzkerM, Feb 07 '14 at 13:09

There is no actual need to flush DNS as Ubuntu doesn't cache DNS. Instead, your ISP may be caching DNS. If you want to enable DNS cache, install pdnsd and resolvconf.

Install nscd using the following command if not yet

sudo apt-get install nscd

Flush DNS Cache in Ubuntu by restarting the nscd

sudo /etc/init.d/nscd restart

@Ask That application only enables DNS caches, as mentioned by AzkerM and me, Ubuntu does not cache DNS by default. – owl Jun 13 '14 at 11:49

Ubuntu 17.04 and onwards use systemd for DNS.

sudo systemd-resolve --flush-caches

All very well, but it is a long way from 13 to 18. – mckenzm Jun 01 '19 at 21:29
