Some comments about draft-huitema-v6ops-teredo-02.txt (a couple of things noticed during implementation): - The Authentication indication should have an alignment requirement of 4n. This is to prevent unnecessary copying of RA and RS messages on platforms that have to worry about memory alignment. - The length of the nonce used in ICMPv6 echo requests and replies is referred only as "a large random number" (3.4) or just as "a random number" (5.2.9). At least a suggestion for the length of the nonce should be given. - In 5.2.3, shouldn't the "If these values match the IPv4 address of the server..." be step 1) of the packet reception procedure? Also the "If the values are different,..." refers to a sentence in the previous paragraph. It would be clearer just to repeat what exactly is different. (IMHO the use of semi-colons makes the text harder to read in especially in packet reception and transmission procedure explanations.)
