Making Network packets

admiralfreezbee has asked for the wisdom of the Perl Monks concerning the following question:

I need to make a data packet to send over a network. All I need is the data the placing in an UDP packet is no problem. The layout of the message is
ID (1 byte) | TransID (3 bytes)
Option_ID (2 bytes) | Option_length (2 bytes)
IP_address (16 bytes)

If anyone is wondering it's a DHCPv6 reply message.
I guess I need to do this with pack but my experience with Perl is very limited. Can anyone help me?

[Corion]: Meh. I need to find myself a better "programming" feed than r/programming (which is just HackerNews reposts and advertisements, very little code). Maybe I should select a list of links that I liked on r/programming and then google for ...
[Corion]: ... an aggregator site that also listed (ideally) all of these links once. And maybe also have an exclude list to blacklist some of the most spammy links that the site may have never mentioned at all
[marto]: I gave up reading HN at all, and feel much better for it :P
[Corion]: Now, how to best automate that Google search ... :-)
[Corion]: marto: Yeah, I'm also short of not reading it at all. I already stopped reading it in the morning because it gave me a foul mood.
[Corion]: The good posts on HN are the non-computing posts. Most of the other stuff is maybe relevant to you if you are 20 and live in Silicon Valley...
[Corion]: Two attributes that don't describe me.
[Corion]: Maybe I should also write a curator for HN or simply not read it anymore, like you do.
