Hello Dan,
Thanks for the reply,
By protocols I meant ipv6 and ipv4 only.
I had a doubt that in the IP layer the datagram has a slot of 1 byte
address for defining the upper layer protocol that is used. At present nmap
has a way of defining what to use tcp,udp or e.t.c.
I was thinking that instead of specifying this can we have a random
selection of the protocol to use which is best for the network architecture.

Thanks,
With regards,
Akash Das

Akash,

What do you mean by the "protocol version"? IP protocol version is either
IPv4 (default) or IPv6 (with -6 option). TCP does not have versions.
