Comparison Between Stateless and Stateful NAT64
Stateless NAT64
Stateful NAT64
1:1 translation, hence applicable for limited number of endpoints
1: N translation, hence no constraint on thenumber of end points therefore, also applicable for carrier grade NAT (CGN) No conservation of IPv4 address Conserves IPv4 address Helps ensure end-to-end address transparency and scalability Uses address overloading; hence lacks end-to-end address transparency No state or bindings created on the translation State or bindings created on every unique translation Requires IPv4-translatable IPv6 address assignment (mandatory requirement) No requirement for the characteristics of IPv6 address assignment Requires either manual or Domain Host Configuration Protocol Version 6 (DHCPv6)-based address assignment for IPv6 hosts Capability to choose any mode of IPv6 address assignment: manual, DHCPv6, or stateless address autoconfiguration (SLAAC)
