[App_rpt-users] DNS Name instead of IP

Is there a way to setup my node(s) to register a DNS name to the ASL server rather than an IP? I'm finding my ISP changes my IP radically (up to the 3rd octet) on almost a daily basis and it takes the ASL server a bit to catch up. Thanks and 73 de K0JSC Sorry for the back to back posts, I was sending from the wrong email address and either one actually made it to the list.
