Yes:
anntaylor.outbound.ed10.com.iddb.isipp.com. 1H IN A 64.14.86.219
219.86.14.64.iadb.isipp.com. 1H IN A 127.0.100.7
219.86.14.64.iadb.isipp.com. 1H IN A 127.0.0.1
219.86.14.64.iadb.isipp.com. 1H IN A 127.0.0.2
219.86.14.64.iadb.isipp.com. 1H IN A 127.0.2.2
Still a bit too sender-centric for my likes, but perhaps workable.

We could use it as a flag to check new records for FPs as
opposed to am outright whitelist.
