Local DNS servers RRS feed

  • Question

  • Hi,

    We are hosting provider and provide windous/linux VPS services. We are using google DNS for name resolution in all our Data center servers. That’s causing bandwidth and connections issues. I’ve just checked it was 235 connections during off peak time and DNS queries were 2nd most highest connections.

    Is that possible can we create a local DNS server that can resolve DNS queries and cache it rather than using google DNS?

    Detail reply is highly appreciated.

  • Yes. Configure the local DNS server to use root hints.

    The DNS server will still need to connect to the Internet to resolve names, but your client computers can avoid going to google DNS for everything.

  • Hi Shoaib Nawaz,

    You may set up a caching-only DNS server locally.

    Caching only DNS server are not authoritative for any domains, they perform queries first, then cache answers.

    For caching-only DNS server, we need to enable the root hints are correct, so that caching-only DNS server can resolve the external domain correctly.

  • Yeah avoid Google DNS, and just put 8.8.8.8 in your root hints. LOL..

    Why not use your local ISP DNS?
