[tlug] LAN domain name naming standards

[Jacques Deguest <jack@example.com>]

Hello,

I would like to get your advice on the following:
I know there are various ways to define the LAN domain. Some use 
something totally fake like company.intern, some uses tokyo.company.jp, etc.
What are the current standards for LAN domain name naming and what are 
the pros and cons considering scalability (Extranet, VPN, Windows 
server, Unixes server softwares) and that the company has several 
branches in Japan?
Do you know good pointers to online reading materials on the subject?

Thanks,
