Ok thanks so would it be better to forward from my local dns server to ISP dns server or us root name servers to access internet please advice

Mohammed HamadaSenior IT ConsultantCommented:
You mean forwarding DNS resolve requests to the ISP ? The DNS is only responsible for the translation of domain names.

If you're talking about something else please clarify .

Normally I use forwarders on my DNS server to forward requests to the ISP to resolve.

You may set your own dns servers to serve your network. This gives you control over DNS resolution.

Basically my local dns server will serve my local queries but for internet access will it be better to have a forwarder to isp for queries like www.google.com or must I use root name server please advice

You can rely on your ISP provider DNS server and forward your external inquires to it.

Having your own DNS server to resolve external inquires will reduce adaptation time to changes in external domains. e.g. if Your ISP dns server cache some external resolutions for say 24 hrs and you cache it for another 24 hrs then changes may take up to 48 hrs.

I think for faster resolution you can use your root name servers but for less pain and configuration you can just use the forwarders to your ISP.
