DNS
Some time ago I read in a computer magazines about using Open DNS or Google DNS rather than an ISPs own DNS. It must have seemed a good idea at the time so I altered my DNS to Google Public DNS 8.8.8.8. Since that time I have had no DNS problems whatsoever. However, I didn't have any problems before the change.
I have no idea what persuaded me to make the change or what advantages ,perceived or actual, the change has given me.
Was it a good idea to make the change and if so what are/were the advantages?
