I wanted to transfer the domain to planet prior to its expiration, it failed, planet gave refund, all ok. but i forgot to renew domain in time with "the old" registar and now he says my domain is in RDP and if I want to renew it should pay about 360$.
Is that possible?
What is RDP?

Or am I being scamed?

In whois info they, and I, are still listed as registars.

It is the redemption period, the fee varies and I am not a big domain registar but that sounds about right.

If you want the domain back - probably what you will have to do.

thx. i'll see what i'll do.

I have my domains at another provider and they have a 45 day redemption policy and then it will be available to the public again.
But that is taking a risk of someone stealing it from you.

All depends on how important the domain is to you and not all registrars have the same policy.

If the domain is important to you, it's taking a big risk to try and wait for it to go public again with so many domain brokers scooping up pre-registered domains and then selling them for $1000 to $2500+ if they're remotely good or popular. If it's a trade name of course you could sue them for squatting, but that too will cost much much more time, effort, and money than the redemption fee

I have decided to pay the fee.
Once i paid to RegFly, and if I survived that, I can certainly survive this

I think you did the right thing, even if it does feel like being ripped off. Then again, I'm not a gambling man; the feeling of losing it after 45 days of waiting though would be much worse. Also I *think* registrars such as Network Solutions and Dotster at least in the past handed expired domains directly over to auction sites like snapnames so the good domains never really do go public anymore after expiring as there is an eager crowd there scanning the list of recently expired domains. And then the big outfits like BuyDomains seem comfortable to sit on a considerable inventory in order to maximize the price of each domain they have even if it takes them years and years to sell a given domain.
