Well, the host from which you sent the mail, 89.233.202.113, does have a 
DNS name: h-89-233-202-113.wholesale.rp80.se (you can see how the IP 
address is encoded in the DNS name). This is typical facility from ISPs 
today. It often works even for dial-up, though it has much less utility 
there.

You should check to see if your IP addresses are truly dynamic. I know 
some ISP (Comcast, e.g.) who use DHCP to assign IP addresses, but which 
never really change, at least not for months on end.

If your ISP has, for practical purposes, reserved a range of IP 
addresses for you, you can, to a first approximation, treat them as 
static and use the corresponding DNS names.

At some point the IP address(es) may be changed, and you'll have to 
adapt. You can probably cobble together some simple scripts to deal 
with that eventuality.
