Need to resolve an IP to a domain name

Question

I need to resolve an IP to a domain name. I have tried Dns.GetHostEntry and it does not work.

 

For example if you just put http://216.58.219.46 in IE or chrome it will automatically resolve to  https://www.google.com/?gws_rd=ssl

 

How can I do this in c#?

 

I am using 2005 express also.
