41. This design means that neither the Teredo server nor client needs to know the IPv4 address of any Teredo relays. 42. The Teredo protocol, also, encapsulates detailed information, about the tunnel's endpoint, in data packets. 43. Commissioned after the end of the Second World War, " Teredo " had a relatively peaceful career. 44. Teredo clients also maintain a binding on their NAT toward their Teredo server by sending a UDP packet at regular intervals.45. Teredo clients also maintain a binding on their NAT toward their Teredo server by sending a UDP packet at regular intervals. 46. They built it from heavy, teredo -resistant Brazilian hardwoods using only adzes, axes, hand saws, and chisels. 47. ;Teredo host-specific relay : A Teredo relay whose range of service is limited to the very host it runs on. 48. ;Teredo host-specific relay : A Teredo relay whose range of service is limited to the very host it runs on. 49. The Teredo server de-capsulates the ping onto the IPv6 Internet, so that the ping should eventually reach the IPv6 node. 50. The original Shipworm specification that led to the final Teredo protocol also supported symmetric NATs, but dropped that due to security concerns.
