What happens if the domain name expires? the renewal charges for an expired domain are same or different ?

I need to know these details as i'm having these similar problems with my offical domain name. The service provider says that your domain as it is expired is into some other place i dont know what name he said but the summary is he said its expensive to renew an expired domain. IS IT CORRECT ??

I always pay the same charge to renew my domains yearly. If a domain expires and the company that owns it sees it as popular I guess they may charge whatever they feel it is worth.

I don't know as it never happened to me- but I wouldn't talk to your service providers about it. I'd talk to the people you bought the domain name from. If you bought it directly from the hosts, that could pose a bit of a problem :(

Either way, you should have been notified that your domain was about to expire, and that a payment should be made to renew it for another whatever years.
