Assigning ARIN IP's to an ISP

My company recently got our own /23 block of IP's from ARIN and are planning how to use them.
We currently have the entire block pointed at our new datacenter (not yet in use), but right now will only need a /27 there, so I'm wondering if it's possible to change the configuration, point a /27 block to the ISP at our datacenter, and leave the rest "unpointed" for now, so we can assign them to other connections in the future. Of course I don't want to lose them.

Any help would be appreciated. Thanks.

If you have an allocation from ARIN, you have three options for providing those IPs to customers:

1) reallocation (used if the customer needs to allocate further)
2) complex assignment
3) simple assignment (this is what I use most of the time for assignments)

You will SWIP the subnet from your allocation to your customer.  You can do that (I believe) via the ARIN web page or via email.

This strikes me as an odd question.  Is your ISP not already involved in routing those IPs - even the "unused" ones?  If not, how are you advertising routes to your network(s)?

I'm guessing the answer to your question is just a phone call (to your ISP) away.  Just tell them what your address space is and how you want things divvied up.  I'm sure they'll help you.

There are too many upstream routers that will drop anything smaller than a /24 or /25.

You really need to receive the entire /23, do your assignments and route downstream from there.

It sounds more like you need internal routing assistance.
