I just updated DNS records on one of my customer’s website, and now the DNS record is not updating. The website is still pointing towards the old domain. I guess it is with my ISP’s DNS Cache. I thought to clear the DNS records of my system, which is Ubuntu by default.
And I found out that the Ubuntu does not uses a DNS cache. I will try to dig deeper into it.And yeah you can use the following command to check out and dig about your domain 😛
