The historical data is available for query now in RIPE. The ARIN service WhoWas requires a formal request and is not a realtime or programatic method to access the data. The specific issue here is retaining the current historical versioning available in a case where a block is subdivided and the original block no longer exists and making sure associated objects also get cleaned up.

Not sure if this is still in Beta? I don't know the the process or policy of each RIR and am more familiar with ARIN. ARIN does not get rid of historical information. They keep the records and make the information available through a service called WhoWas. https://www.arin.net/resources/whowas/index.html --Heather On Thu, Feb 12, 2015 at 2:38 PM, William Sylvester <william.sylvester@addrex.net<mailto:william.sylvester@addrex.net>> wrote: Hi, I support this and also was wondering about associated objects like routing objects and in-addrs? This is also an issue for claiming an old block where a locked maintainer was used. It would be nice to have the unlocked maintainer apply for objects related to the block not just the inetnum for example.
