In reviewing IPv6 end user allocation policies, I can find little agreement on what prefix length is appropriate for residential end users. /64 and /56 seem to be the favorite candidates, with /56 being slightly preferred.
I am most curious as to why a /60 prefix is not considered when trying to address this problem. It provides 16 /64 subnetworks, which seems like an adequate amount for an end user.
Does anyone have opinions on the BCP for end user addressing in IPv6?
For business customers I would give /48 and home users who might have 1-2 subnet I would give /56 or /60. Reasons: - Business customers night grow where you have to provide bigger amount of subnet - allow space for future extension -
- Home users - they usually don't know what is subnet. Setting up different subnets in their SOHO router can be difficult. Usually the simple 1 subnet for every device is enough for them. Separating some devices into a separate subnets is usually enough for the most sophisticated home users. If not then he can opt for business service….
This utterly ignores the reality of DHCPv6, DHCP-PD, and technologies currently being developed for rational automatic hierarchies of topology. Owen
