5. Stateless Address Mapping Algorithm

If a pool of public IPv4 addresses is configured on the translator, it is RECOMMENDED to randomly select the IPv4 source address from the pool. Random selection reduces the probability that two ICMP messages elicited by the same TRACEROUTE might specify the same source address and, therefore, erroneously present the appearance of a routing loop.

[RFC5837] extensions and an enhanced traceroute application, if used, will reveal the IPv6 source addresses that generated the original ICMPv6 messages.
