Q I travel a fair bit, both within the UK and, less frequently, in Europe. What is the best way to get a reliable Name Service when on the road?

A If you haven’t done so, in the Network pane, create yourself a new Location profile. Set this up with WiFi enabled and other settings suitable for your trips. In the DNS Server box, insert the two IP addresses for OpenDNS: 208.67.222.222 and 208.67.220.220.

OpenDNS offers free and paid-for services from its network of DNS servers around the world. Using those two IP addresses should always connect you to the nearest of their servers.

They are DNS specialists, leading in DNS and related security research. You should find their service quicker, more reliable than local providers, and much more secure.
