No, I mean public IPv4 address. As in, publicly routeable. I'm on
Comcast residential, so DHCP, but I have a publicly routable IPv4
address (71.205.113.62, at the moment). It just changes every few
weeks.

I'm using a different script, but yeah.

Ouch.

My understanding of ADSL is that non-primary* ADSL providers have
their traffic routed through the primary's network on a tagged vlan,
until it comes out at the ISP's POP. IIRC, I did find an ADSL provider
in Seattle which could give me (in Grand Rapids) native IPv6, but my
packets would be bouncing across the country.

* Don't know the exact term, sorry. Primary being the physical owner,
non-primary being the ones who lease.
