#23 — How to interpret newsgroup headers

Below are some typical headers. I'm just wondering what each group of characters means. Some change during use, some change when the power is turned off. Others stay the same. Just curious. 

If there is a newsgroups specific to headers, I would ask someone to please let me know. 

Thanks in advance.

PS - It's easier to see the grouping using a fixed font.

Are you asking how to interpret Message IDs? Each newsreader has its 
own, ideosyncratic method for generating them. They're generally a 
combination of some characters that are generated from information 
unique to the client machine, so they won't conflict with posts from 
other clients, and some characters generated from the posting time, so 
that messages from the same client will not have duplicate IDs.

In your case, I'd guess the RHD5iwII3 part is the machine-specific part, 
while the stuff to the left of it comes from the time.

And the OP can read more about them e.g. here:

  https://tools.ietf.org/html/rfc3977
  Network News Transfer Protocol (NNTP)
  A.2.  Message-IDs

rfc5536 specifies article header interpretation, mostly.

The IETF seems to run this web rfc reader, I didn't see a newsgroup for 
rfc updates: https://www.rfc-editor.org/rfc/rfc5536

Those don't seem to be headers, they seem to be URIs except there seems 
to be whitespace so probably not valid news URIs.
