 | | Shipworm is designed to robustly enable IPv6 traffic through NAT, and the price of robustness is a reasonable amount of overhead, due to UDP encapsulation, transmission of bubbles, and relaying of packets through the Shipworm servers. |
 | | A "Shipworm" is a little saltwater critter that is common in the harbors of warm seas and that digs holes in immersed wood pieces, such as boat hulls or pilings. |
 | | Shipworm packets are always sent from either the Shipworm IPv4 anycast address, or from an IPv4 address and UDP port that is strictly consistent with the encapsulated IPv6 source address; this MUST be checked by servers and clients, as specified in sections 4.2.2 and 4.3.1. |
