I found an article on a forum about testing your DNS for randomness in light 
of the vulnerability there has been of late.
The site is
https://www.dns-oarc.net/oarc/services/dnsentropy
The problem is when I click the button on the page it return a result which is 
ok but the IP address of the dns it checked is not one that I use, it is 
registered to google. My ISP is Virgin (NTL) and the dns entry I use are 
158.43.128.1
158.43.192.1
These DNS were given to me by somebody on here or the Dorset mailing list ages 
ago when NTL were having problems with theirs DNS's.
Am I missing something or plainly barking up the wrong tree
