FC5 i386 or x86_64 which way to go?

[Michael Cohen]

Jim,
  IPv6 is a pain for most networks, and modern distros have it turned on by
  default.  Im all for the benefits of ipv6 but in some networks its best left
  off.

  The main problem is that when ipv6 is turned on the resolver tries to resolve
  AAAA records before A records which means that if your DNS arhitecture does
  not support AAAA records (and many adsl/routers do not) it will need to time
  out the first query before the resolver tries for A records.

  This means that all resolutions will take about 2 seconds to complete which
  really slows down most systems. 

  The problem is that you cant rmmod ipv6. There is a way to disable it in
  modules.conf, but I generally just delete the module from the /lib/modules/
  directory which works just as well.

  Michael.
