Especially for "legacy" assignments, done by InterNIC to a company that has been sold and bought 5 times in the meantime...
In the case of ARIN, you have to sign a new Registration Services Agreement if the company name changes. I just went through this for resources registered to CompanyName, Inc. where the network assets are now owned by CompanyName Americas, Inc. Same company name, but ARIN requires the Registration Services Agreement to be formally signed by an officer of the new corporate name. I'm beginning to think that it was simple the *WRONG* decision to try and bundle together the issue of registration services contracts for PI assignments going forward, and migrating existing PI holders into a contractual relationship. I believe we have consensus on requiring a contract to be signed for any future assignments/allocations. --Michael Dillon
