Perhaps...

Quite correct.   The operational need for address space can indeed by “internal”; i.e. not routed on the greater Internet.

Also all correct, but I will note that in the above case there is some form of networking services being provided and thus require the use of unique addresses to make it happen.   Again, the routing to the greater internet isn’t necessarily a component to having the need for IP address space to provide networking services.

You have read “connectivity” to be “routed on the greater Internet” and yet we’re all aware that there are many useful networking services that don’t equate - a broadband connection to one’s home may only route a single IP to the greater Internet, but all the devices inside still benefit from the network service provided.  Even if the network service provided is entirely internal, there is still networking involved and thus an operational need for IP address to make such networking work. 

In the ARIN region, if you request IP address space, we assess that per the community-developed Number Resource Policy Manual, i.e. <https://www.arin.net/participate/policy/nrpm/ <https://www.arin.net/participate/policy/nrpm/>>   All assignments are made accordingly to “operational need” even to this day - i.e. you have to have some actual networking requirement if you are to be issued an IP address block, although this doesn’t equate to “must be routed on the public Internet”.   

Do we have parties who postulate their operational need based on entirely internal services, or services that live within virtual devices in a data center?   Sure…  and some of these are indeed legitimate and fulfilled per policy.  We also have folks who get creative and make similar requests for purposes of obtaining address blocks from ARIN – absent any bona fide networking need –for subsequent monetization and these reviewed, revoked, and can be referred to criminal fraud proceedings.   

For those who need IP address blocks for their network operation, it’s really not complicated – you can call, email, or chat with the ARIN Helpdesk and we’ll work you through it.   I don’t know about the policy in the other region, but can state unequivocally that if you call with the need for IP address space for an actual operational networking situation, we’ll do our best to help you with your request and get it approved based on whatever the policies allow.   I can also say that if one's purported operational need for address space is "for reassignment to customers but completely absent any networking service”, then don’t bother applying to ARIN – the policies do not provide for issuance under such circumstances and have never in the ARIN region.
