Hi, this is not a problem but rather curiousity.

My mother-in-law was having problems getting FaceTime to connect on her new iPad2 - so I googled for her and quite a few suggestions said to change the DNS address to 8.8.8.8. so I did and it worked.

Just curious to know what is DNS, and why did changing the numbers help FaceTime to work?

That ip belongs to Google. Sometimes, it maybe better than your ISP's DNS servers. If its not on Auto, (If you put in an ip address manually). if the DNS servers are stuffed, you wont get on the internet

This is what DNS means

DNS basically changes "pressf1.co.nz" into an IP Address of "210.48.100.45" which it can then use to find the server that your website / service is hosted from.

Many ISP's have DNS issues over the years, it's a relatively common occurrence that they break things, so I'm a big fan of the likes of Google DNS / OpenDNS!

Now I understand what DNS is - I still don't quite get how changing the DNS address helped FaceTime to work?

Basically the automatic ISP-supplied DNS would have been fubar'd, giving the wrong information or something to your device, breaking Facetime.
Using Google DNS has allowed it to find the correct servers thereby fixing Facetime :)
