You could loose your ru-domain

As RIPN, the Russian registry reports, RIPN stops to perform
the duties of .RU Second Level Domain Names Registrar from 2005
January 01. But RIPN remains the operator of the ru-registry and
continues to provide technical support of Domain Name
Registration System and name servers of ru-domains. It will stay
also registrar concerning org.ru-domains , net.ru-domains ,
.pp.ru-domains and com.ru-domains Therefore all Second Level
Domain NameRegistration Agreements between RIPN and persons or
entities will be terminated from January 01, 2005.

It will be impossible to extend registration terms of ru-domains
sponsored by RIPN after the termination of the Second Level
Domain Name Registration Agreements. All ru-domains registered
before January 01, 2005 will be supported by RIPN till
expiration date. To maintain and renew the domain name
registrations of existing ru-domains it is necessary to transfer
domains sponsorship to another active registrar.
