Alexander,

Do you mean that the prefix is being used as specified in RFC1888 or in some other way?

On a technical detail, the prefix is marked as "reserved" by IANA. The logic for that is that if anybody is using 0200::/7 on the public Internet for its original experimental purpose, it cannot also be used for any other purpose. What is "deprecated" is the method in RFC1888.

Regards
   Brian Carpenter
