Not unless @home gave you a classless in-addr.arpa delegation. Otherwise, no one besides yourself will attempt to query your nameservers for PTR info. This error is so common, even at my place of work. People assume if they register a blahblah.com domain, and set up name servers, they automatically control the in-addr.arpa zone as well. In fact these are two distinct namespaces and can be (and often is) under separate administrative management. Now, your ISP may or may not grant you delegation - they won't for a /27 probably but might for a /24. If not, they should add/update the PTR records on your behalf. If they do not, they suck.
