This proposal aims to describe some situations while unique requests

may be occurred during the IPv4 allocation transfer processes between LIRs. 

APNIC IPv4 Address Policy DID provide guidelines of the address space

management for the special conditions, such as mergers, acquisitions, and

takeovers of LIRs.  For example, the Policy mentions that all of the address

space assigned to the eliminated LIR previously must be reviewed or returned

back to APNIC after those transformations completed.

However, with our experience, there were cases may need different

solutions/extra guidelines to resolve some problems attached. 

For instance, it may not be sufficient to utilize the same approaches to handle

requests occurred due to the changes of some services or subsidiary, instead

of the whole company, shifted from ISP A to ISP B.  Moreover, an idea of

customers would like to keep the same IP resource (e.g. fixed IP) during any

transfers occurred between LIRs or ISPs, may be need to take into consideration

of policy making.

On the other hand, if the partial IPv4 allocation transfer between LIRs are permitted,

some suggested guidelines must be considered. For example, the size of the minimal unit,

ie. the minimal allocation, is needed be claimed for the partial allocated address space transfer.
