I already bought a domain name .com on godaddy for my company.

I would like to reserve the same name with country specific domain extention, but not sure where to buy them and how to do it.

Here are the ones that I would like to buy: Europe: fr, co.uk, de, ch, es, it, nl, se, no, ru australia: com.au asia: sg

Godaddy has all except 1 in europe, australia and singapore. Should I find a website that sell all of them or should I buy some of them in godaddy and others elsewhere? Any suggestions where to buy them?

Until now i've always buy .com domain names only so not sure how to do it. Thanks
