They have probably done the reverse lookup already. IIRC, the reverse DNS for a single IP address can not be handed off to you by the ISP without some interesting tricks. The ISP that my job uses allowed us to do reverse DNS for our 16 IPs, but they did some interesting tricks with CNAME records to do it. The catch of this is that the reverse and forward lookups are unlikely to match. For example, you might want www.example.com --> 1.2.3.4 and 4.3.2.1.in-addr.arpa --> www.example.com. However, the ISP has already set up 4.3.2.1.in-addr.arpa --> customer15.dialup.isp.com. This would mean that your DNS wouldn't be www.example.com-->1.2.3.4-->www.example.com (as it should be) but would be www.example.com-->1.2.3.4-->customer15.dialup.isp.com. This isn't tragic in most situations, but its not perfect. Talk to your ISP for details.
