Is that possible to have unmetered traffic from the hosting company which provide dedicated servers, I mean SHILL SPAM REMOVED

Of course - unmetered only means that you don't measure it... it's not the same thing as "unlimited" and typically unmetered means there is a low speed limit applied (traffic shaping) - not that they advertise or maybe even admit to it - or otherwise a high contention ratio; for example a large number of customers sharing a 100Mbps uplink or similar.

I've seen providers offering 10Mbps unmetered on 5:1 contention for example. It isn't necessarily a bad thing as it depends on your specific requirements, but you should know what you're buying and match it against your needs accordingly.

Personally I much prefer a fully burstable port speed link with a minimum rate guaranteed between my server and upstream transits (obviously there is no way to guarantee a speed the whole way from a server to you / your users unless there is a point to point link or similar).

Thanks for your reply.
More opinions?

Well there's not really much more "opinion".

unmetered traffic - is that possible?

Yes. That's pretty much all you can say as there is only 1 answer; yes, you can not measure the traffic usage and thus it becomes unmetered by definition.

However, since you're looking for more input I suppose your question is maybe a bit different to stated? Do you mean to ask opinion's if it's a good idea? (good for who - providers or customers?)

I believe that would be really good idea to get in touch with particular web hosting provider and ask them.
Only they will be able to explain you what unlettered service includes.

Want to know the pricing policy of SHILL SPAM REMOVED company?
Are their dedis fully-managed?

Unmetered means the host doesn't pay attention to what you use so it is possible but I think it is unrealistic and I'd rather go with a limited variant because unmetered hosting leaves a lot to be desired I think.

I pay a set price for set boundaries and it is working out great for me.

It's possible until your datacenter starts to yell at you for excessive bandwidth usage

Check their tos first to see if it is unmetered or it is unmetered for some MB's of bandwidth and then it goes down.
