Thanks for taking this on! :slightly_smiling_face:

I'm going to approach this as if you're actually addressing issue #94 as it's a superset of #76

Noticed a couple of things we still need to check:

• does version_major fit within the single byte available
  • https://github.com/eclipse-uprotocol/up-java/pull/97/files#diff-d0045eec4843c856c7d51a9b2e3c1efb9b36b7ee476963b7767dea309dfeee86R146
• is the length of the ID [1, 255]
  • current check makes sure it's not greater than 255, but doesn't make sure it's not 0
  • https://github.com/eclipse-uprotocol/up-java/pull/97/files#diff-d0045eec4843c856c7d51a9b2e3c1efb9b36b7ee476963b7767dea309dfeee86R158
• if it's an IP address is it 4 or 16 bytes
  • https://github.com/eclipse-uprotocol/up-java/pull/97/files#diff-d0045eec4843c856c7d51a9b2e3c1efb9b36b7ee476963b7767dea309dfeee86R166

Also some general feedback -- I think it'd be a little cleaner to separate the validation logic out from the serialization itself.

For reference, here's the PR from up-rust which did this change.

(edited to add some references to the relevant code sections)

@stevenhartley, @neelam-kushwah -- I left some feedback in this comment which was not addressed.

Is the plan to make a follow-up PR?
