The access-control argument has been beaten to death already. We offer our
customers static IP addresses for some additional reasons:
  - ability to receive mail by SMTP instead of POP
  - ability to run a part time WWW or BBS service at a fixed address
  - support for systems that don't easily support dynamic addresses 
    (some Unix machines with hand-coded dialup scripts)
and most importantly
  - ability to do disconnect-and-redial without breaking connections, which
    is particularly useful with ISDN. You can telnet somewhere, get idled out
    of the ISDN server, hit return and your ISDN adapter auto-redials and
    connects and your packet goes through, and you're still on the same
    address so everything works.
    Customers on flakey dialup lines (28.8k from up in the mountains during
    bad weather) appreciate this too.
