As long as your upstreams/partners are cool with that, there is no related designation between how addresses are allocated versus how they are announced. In other words, TECHNICALLY you could advertise a whole bunch of /30's.... You just run the risk of being filtered and/or ridiculed along the way. :) But splitting the /22's from the same announcing AS shouldn't cause any problems as long as you design your connectivity ok.

I have an ARIN /21 assignment and a new requirement for a second data center. Rather than ask for another assignment, I would like to advertise one /22 from one location and the other /22 from the second location both with the same asn. My apps will work that way, so I don't have an issue internally, but I'm looking for a broader base opinion on that. Thanks a lot! -James
