Why enterprise IT needs an IPv6 addressing plan • It helps them accurately gauge the size and type of IPv6 allocation their organization needs ̶ This helps ensure that their ultimate addressing plan retains its scalability and flexibility, meeting the network growth and change requirements in the years to come • It requires a baseline of IPv6 knowledge and training that will help facilitate other IPv6 adoption plan tasks and IPv6 operations 4 4 || ©©2015 2013 Infoblox Infoblox Inc.

Standard IPv6 Allocation Sizes • Most enterprises should receive a minimum of a /32 to a /44 • Generally, one /48 per site 7 7 || ©©2015 2013 Infoblox Infoblox Inc. Inc. All All Rights Rights Reserved.Reserved. What constitutes a site? • Characteristics of sites in IPv6 ̶ Logical construct ̶ Definition that makes operational sense - Based on network topology, routing and security policy, etc - Based on what best maximizes operational efficiency ̶ Often assigned a /48 - Sites can receive larger or smaller allocations depending on what makes operational sense – Address conservation generally not a concern ̶ Not enough /48s? Back to the RIR or ISP - RIRs hold contiguous bits in reserve 8 8 || ©©2015 2013 Infoblox Infoblox Inc. Inc. All All Rights Rights Reserved.Reserved.
