Unexpected inet6 in FreeBSD 4.9-STABLE

[Chris Pepper]

	I have two systems, named www & guest. Both are tracking 
FreeBSD 4.9-STABLE, but guest is a bit more current. Neither has IPv6 
explicitly enabled, but for some reason, guest insists on configuring 
an inet6 interface at boot time ("ifconfig xl0" shows an additional 
inet6 address line, not present on www).

	This is causing me some aggravation, as localhost connections 
(such as "apachectl fullstatus") are from "[client ::1]" instead of 
the old-fashioned  127.0.0.1. To my surprise, 
<http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-ipv6.html> 
doesn't talk about rc.conf at all, and I'm not sure where else this 
would be set up.

	Suggestions, references for further reading, or pointers to 
the obvious bit which I'm missing all welcomed (please CC me 
directly).
