The use case I was thinking of was in getting DNS messages over UDP through, not larger than 1<<16 message sizes. Because there is no sequence in UDP, it'd also need the index and count in every segment/fragment. I didn't mention label sequence compression in the prior message. In the case of fragments over UDP, message compression would occur as before (RFC 1035) where OFFSET is valid within a datagram (fragment). As offsets do not cross datagram boundaries, this would aid simple implemementation. Mukund
