redhat docs say: "to disable IPV6"

[Fred Silsbee]

To do this, first remove this line from /etc/modprobe.conf if this line exists. (Most Red Hat Enterprise Linux systems will not have one).

alias net-pf-10 ipv6

Next, add the following line to /etc/modprobe.conf:

alias net-pf-10 off

Reboot the system. IPv6 support should now be disabled.

I disabled IPV6 once and there were several places:

in /etc/profile.d/kde.csh there is

## if not using IPv6, speeds DNS operations
# if ( ! $?KDE_NO_IPV6 ) setenv KDE_NO_IPV6 1

also /etc/Muttrc

do a 
>cd /etc
>grep -iR ipv6 .|more
