Actually, ipv6 takes <i>less</i> implementation work from a network operations standpoint. Every site gets a fixed size network, every building gets a fixed size network, every vlan gets a fixed size network. No more IP budgeting and wrangling nabout justifying IP allocations. &quot;Is that worthy of a &#x2F;18 or should it be a &#x2F;20?&quot; That&#x27;s all gone. Every vlan with people gets a &#x2F;64 and your router interface to them is fe80::1. Turn on SLAAC and let it run. No more NAT pools and rules. It&#x27;s great!
