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.)

Thanks,
