Warning When Using OpenDNS

[Jamie Paul Griffin]

Hi

I was looking into additional online security measure a while ago. I cam across some info discussing the benefits of using OpenDNS name servers which I then decided to try. 

Since doing that, port prints a warning: Warning: Your DNS servers incorrectly claim to know the address of nonexistent hosts. This may cause checksum mismatches for some ports.

What are the thoughts on this, is using their name servers beneficial and will it likely cause issues when using port?

Cheers, Jamie.
