This question already has an answer here:
I'm currently building a private servers farm with a thousand and thousand hosts, and I suddenly faced a really interesting question that I was unable to answer at the moment.
Is there a Standard ISO/Whatever for servers hostname attribution into a really large environnement?
For now, my puppet generate a random alphanumeric hostname that it not relevant for anyone connecting on the host.
That fine, and I'm able to connect to the correct server and service for maintenance because my puppet is managing all my host and link them to Nagios which has category etc.
But I'm really interesting to know if someone already faced this kind of question AND/OR if you have personal experience and testimony.
