Re: need to disable IPv6

I asked:

"modstat" doesn't list any modules at all.

Cool!  That removed the IPv6 address from the external interface!
However that doesn't seem to affect how a request involving an IPv6
address is handled.  The good news is that I immediately get "No route
to host" either way.

(Yes, that's exactly what happens.)

(It is zero.)

Thanks for that info.

Well, after all that, it wasn't.  Firefox must have got itself into a
funny state, because killing and restarting it have cleared up the
maps problem.  I should have tried that earlier, but everything else
(other web pages, even javascripty ones) seemed to work fine.  Hmf.

Anyway, many thanks to you all for your help; I learned a few
things, so nothing was wasted!
