So that being the case, how would a machine decide which network card to use
to get its internet access? say for example the machine has 3 network
connections and each machine connected on the other end has an internet
connection. How would the computer then decide which one to use?
Surely they cannot all have a default gateway set at the same time can they?

I will take a look at that service. I vaguely remember checking them out a
while back but for some reason went with freedns instead. I'll take another
look. do they charge to use their service or are they free like freedns? -
Do they allow you to use your own TLD free?

Nope, freedns allow you to you your own TLD for free. No limit either
however they do allow other people to create subdomains under your domain
though you pre-approve or reject them.

Yes I realise this - Its like everything in the IT world - protocols &
standards for all to follow etc.

To be honest, I never checked out their response codes. Nothing is mentioned
about it on their website (which is rather lacking in detailed documentation
though they've tried).
