Guys, the initial question of OP was clear - can it happen, that domain he holds and has standard renewal attached to it, will change, and it will suddenly have premium renewal attached to it by registry decision (which can be btw higher or lower then standard renewal for given extension), while he still holds the domain name....
And the answer is that this can NOT happen. If you disagree, please give 1 example of when that happened. I am not aware of any single example like that, and would like to learn if there is any.
Thread becomes imho uninformative, as some members are putting here some other information, regarding hikes in prices of standard renewals, etc. This is all true, prices of
standard renewals can increase or decrease if registry decides so, as all of us know very well, but this has nothing to do with initial question ... if someone is new to this, he must be totally confused from the information he was given in this thread.
For
@Internet.Domains, whether name has attached standard or premium renewal, this is the single most important information about new gTLD name you can have. When it is
standard renewal, you can use various promotions which are very frequent in new gTLDs, and regularly can save you as much as 90% of the renewal fee. Those promotions repeat every year for some extensions, and make investing in new gTLDs very pleasant.
If your name has
premium renewals attached to it, you need to understand that possibility of using transfer/renewal promotions is often very limited, for some cases non-existent. It is therefore very important to understand how to check whether your name has standard or premium renewals attached to it.
