Need /24 (arin) asap

Assuming IPv6+translation, yes, you need IPv4 addresses of Good Repute 
for the outside; that might requiring constant monitoring, and notifying 
various content that it's shared address space. It's the same 
operational problem as CGNAT44, but reduced because half (or more) of 
your traffic is using unshared IPv6. Among other things, that means you 
don't need as many IPv4 addresses.

"But wait!" you say, because you're clever, "The original poster only 
wanted a /24. Surely you're not saying you could put less than a /24 
outside your CGN (44 or 64) and have it routed?"

Maybe the /28 is part of your larger aggregate. Or maybe it's a shared 
translator, handling, say, eight small companies who only need a /28 
each. And yes, you want very careful reputation monitoring in that case, 
and maybe some effort to prevent things that get one placed on Lists of 
Addresses of Ill Repute.

Sales pitch available on demand.
