Ideas for Host names and DNS naming formats

[romanroma]

I am looking for ideas on what works best for hostnames and DNS naming format. How do you logically breakout or name your devices?

Hello, 

Today i'm using these format:

SWA-PBLEXP-01

where: SW= SWITCH A= ACCESS, PBL= BUSINESS NAME, EXP= NAME OF DEPARTMENT, 01= QUANTITY OF DEVICES AT THIS PLACE.

SWC-PBLDTC-01

SW= SWITCH C= CORE, PBL= BUSINESS NAME, DTC= DATACENTER, 01= QUANTITY OF DEVICES AT THIS PLACE.

I hope that it can help you.

Please, rate all post that was help you.

Thanks in advance.

Thank you for your suggestions. I have the same type of network, where I have campus and data center. Currently, I have a mix of hostnames and DNS names, which I want to fix and make a uniform format.

I know that changing hostnames will require SSH keys to be rekeyed, so due to the latter, I am thinking of just changing DNS names.

You have a great format, that shows which layer of operation that I like. Example: Access, Distribution, CORE.

Do you do anything different for remote office locations? Or does that just fall under the 'business name' and/or 'department'?

Thank you

for devices that have directly communication with remote sites, we have a difference,  

for exemple: RTC-PBLSP-01 and RTC-PBLMNS-01

where rtc is router-core
