DNS Always Getting Non-Authoritative Answer
Solution 1:
I don't:
[me@risby me]$ nslookup www.yesecommerce.com ns.123-reg.co.uk
Server: ns.123-reg.co.uk
Address: 212.67.202.2#53
Name: www.yesecommerce.com
Address: 92.19.219.18
Some ISPs do transparent proxying of DNS requests; it may be that your ISP is amongst them. The fact that we get consistently different A records returned points in that direction, too.
