The key difference between IPv4 and IPv6 is that in IPv6 we are no longer concerned with address conservation for the purpose of ensuring sufficient host addresses. As a result, the atomic unit of IPv6 address planning is a subnet (of at least a /64 or larger). Allocate or assign subnets in a way that leave many in reserve for future use. It’s important for keeping your IPv6 addressing plan viable that you leave sufficient subnets in reserve for growth. By adhering to nibble boundaries in assigning groups of subnets to your hierarchy, sparse allocation can be automatically accomplished. In addition, practicing a 75% utilized maximum before assigning the next available block of subnets will always leave at least 1/4 of the subnets in reserve for future use. Define a site in a way that best fits your organization’s operational and administrative needs. The number of sites you have will determine the initial size of your IPv6 allocation. Define as many of the different kinds of sites you have in your organization. For example, sites can be geographical (HQ, campus, regional office, etc) or functional (data center, remote office, lab, etc). Internally, sites may have varying levels of required hierarchy (e.g., VLANs, groups of users, subnets to be aggregated, security policy and ACL entries to define, etc). You’ll need at least one or more /64 subnets per level of hierarchy. A minimum of 16 (with up to 12 for immediate use) is recommended; i.e., a /60. The greater the complexity or size of the site, the more groups of subnets will be needed to accommodate the hierarchy of the site; e.g., /56, /52. Keep this in mind when defining your basic site definition. If there is any uncertainty, a /48 per site is recommended." IPv6 Principles 1 2 3 © 2015 Infoblox Inc.

Plan for number of subnets not number of host addresses.

The key di�erence between IPv4 and IPv6 is that in IPv6 we are no longer concerned with address conservation for the purpose of ensuring su�cient host addresses. As a result, the atomic unit of IPv6 address planning is a subnet (of at least a /64 or larger).

Allocate or assign subnets in a way that leave many in reserve for future use.

It’s important for keeping your IPv6 addressing plan viable that you leave su�cient subnets in reserve for growth.

By adhering to nibble boundaries in assigning groups of subnets to your hierarchy, sparse allocation can be automatically accomplished.

In addition, practicing a 75% utilized maximum before assigning the next available block of subnets will always leave at least 1/4 of the subnets in reserve for future use.

Define a site in a way that best fits your organization’s operational and administrative needs.

The number of sites you have will determine the initial size of your IPv6 allocation.

Define as many of the di�erent kinds of sites you have in your organization. For example, sites can be geographical (HQ, campus, regional o�ce, etc) or functional (data center, remote o�ce, lab, etc).

Internally, sites may have varying levels of required hierarchy (e.g., VLANs, groups of users, subnets to be aggregated, security policy and ACL entries to define, etc). You’ll need at least one or more /64 subnets per level of hierarchy. A minimum of 16 (with up to 12 for immediate use) is recommended; i.e., a /60.
