If you're still only going through one AS number, then they're going to have
an aggregate route above that anyway, and absorb your more specific
announcement.
They just static'd to you. You'll just need to talk with them, but there's
no technical reason things shouldn't be ok. On the other hand, they may
take back the /22 if you have your own /21. I would anyway. :)

Subject: About ISP address announcement
hi group:
I have a question and need your help:
we rent IP add 85.1.0.0/22 from ISPA before, and we used default route to
upstream ISP A.
but now, we applied public AS number and IP address 99.1.0.0/21 ourself. we
are going to BGP connect to Upstream ISP A. I am confused with the old IP
address 85.1.0.0/22. This IP address block is blong to ISP A, if we use BGP
connection, this IP address origin from our AS number, not from ISPA AS
number.
I think it will work fine, but i do not know if it is illegal.how to do with
it.
thanks.
Woody
