From the point of view of a PlanetHoster customer, redemption fees are very high. We understand: it is very frustrating to feel like you are paying for nothing! However, when you see that PlanetHoster has no control over this, you will understand better.
If you fail to renew a domain name when asked to do so, it will expire after the “Renewal Grace Period”. You have 30 days in which to request that it be reallocated to you, before it becomes available to anyone on the Web: this is known as the “Redemption Grace Period”.
However, the “redemption fees” incurred are charged by the registries, the commercial companies accredited by ICANN that must maintain a database for each extension. This is why PlanetHoster can unfortunately do nothing about this.
