Gosh, where did you find all of those?
Some I knew, some I didn’t – cool!

Interesting post. I didn’t know there are so many extensions besides the dot com and dot nets.
By the way, I have linked to your blog. Cheers.

Hello, It’s very useful to explain that to readers.
I have just noticed that my today’s post is almost on the same topic. Basically I’m explaining the importance of having those extensions.

Luke Zets last blog post..Be First! Secure Domain Extensions
That is wonderful information. I had no idea what any of them meant. The only one I am familiar with is .com. So not a computer girl! thanks

2 Toronto Search Engine Optimization:
It’s also expensive to register such domain name.. It costs $200.00 for a 2 year registration term! 
Yeah.. I guess so..
2 Nicole:
Uhm.. Just before I registered BioTecK.net I wanted to know my choices for a domain name extension and then I found this somewhere on a ISP list of domain name extension which you could register..
Some of them I knew before but some of them were new for me too.
2 Jeflin:
Beside the .com, .net almost every country got it’s own domain name extension.. 
Cool, thnx for linking to my blog!
2 Luke Zet:
It’s very important to choose your domain name wisely indeed. Before having BioTecK.net I used to blog at BioTecK.nl (Yep, The Netherlands!). In the beginning it was fine cause I wanted to blog in Dutch.. But when I started to blog in English I noticed that I didn’t had much readers, subscriptions and my favorite one: Comments…
So I decided to change that and right now I’ve a lot more visitors, 51 subscriptions and a lot of people who’re kind enough to leave comments. So it’s very important to choose your domain name wisely!
2 Heidi:
As you can see there are a lot other domain name extensions beside .com. 
I’m glad that I could give you valuable information.
These are not called domain name extensions but rather top-level domains (TLDs).
This is a great site…I stopped to drop and had a look around as I usually do to new droppers on my blog…very interesting and informative at the same time!
I’m using the older version of FireFox…love it compared to the other guy…so much faster less issues…will have to check out FireFox 3…enjoy your day…
Cheers

2 Anon:
I know but not everyone knows that and that’s why I choose to use domain name extensions. This way everybody knows what the post is about.
2 Heather:
Feel free to welcome back anytime you want! 
You really should install it..:)
Thnx for dropping and your comment.
FireFox is indeed a lot better and faster!
Thanks for this Domain Name Extension Explaination , nice blog and have a nice day
I didn’t know there was a .name or .musuem, interesting. I knew .ca was Canada.
Happy Birthday!

Hey
Have a great weekend..!!!
tazdogs last blog post..Surprise Thunderstorm for you
I suppose all these extensions are just guidelines really. For example, my site is a .com but it is not a commercial site. It is handy to find all of these listed in one place like this.

Have a nice day too.
No problem!
2 Lisa’s Chaos:
Thnx! I had a wonderful day!
I have heard rumors about some new domain name extension such as .sex, .crap etc.. :S
2 Tazdog:
Thnx a lot! Have a nice weekend too.
2 Sailor:
You’re right. If you got a .com it doesn’t mean that you have a commercial site but .com stands for commercial.
I just read recently that .TV is actually the extension for a very small country so they started selling off domain names for television which is what we now associate that extension with.
It’s actually for a country (i’ll have to look up which one).
Don’t forget to mention how much it might cost to GET one of these extensions….

Hello Pam,
I know about .tv and you’re right.
You might have overlooked it but I have it listed in the International domain name extension as well as domain name extension sorted by extension.
.tv stands for: Tanzania.
About the costs: It’s not that much to get your own domain name. I have paid €15 for my .net and the same amount for my old domain name extension .nl. So it’s not that much..
It’s the hosting part which can be expensive.

You misunderstand. If I wanted to buy “.pam” or something, an actual EXTENSION, it would be a LOT more than the cost of getting ahold of a domain name on ‘.com’ or ‘.net’ or even ‘.tv’ THAT is what I thought was interesting.
I pondered getting one recently… I don’t know all the ins & outs so I’m probably going to focus on higher priority things for me for the moment.
Thanks for writing,
Pam Hoffman

p.s. the list with countries is partially covered on my browser window, yes, i see .tv now! pam
Pam Hoffmans last blog post..Columbus Startup Weekend
Hello Pam,
I’m sure that some of the domain name extensions can be more expensive then other ones, but I was actually talking about getting a .nl, .net, .org, .com domain name extensions..
I’ve read that it’s possible to register ANY domain name extension if you’re willing to pay $100,000.
So you’re right about the high cost!
Thank you so much for publishing this post, this little Thailand fan here appreciates it!
Hint for all Thailand fans: A great resource for everybody interested in Thailand is thai-stars.com which basically is a huge Thailand archive listing everything one needs to know about the Land Of Smiles.
