Underscores in Polycom hostnames

[ Edited ]

Why does Polycom use an underscore in the hostnames of phones when this is in violation of the intention of several RFCs?

 

It causes bind logs to fill with such as: zone somecompany.com/IN: Polycom_XXXXXXXXXXXX.somecompany.com/A: bad owner name (check-names)

Re: Underscores in Polycom hostnames

Hello Chris_,

welcome back to the Polycom Community.

The extended host name syntax is a UTF-8 [RFC3629]  string so therefore we have always been using this type of string.

 

The "older" RFC 1035 does not allow the usage of underscore but again we hardly ever have a customer complain about this.

 

The FAQ contains:

 

Aug 10, 2016 Question:Can I change the Hostname of my Polycom phone?

Explanation:Please check => here <=

 

You can simply manually change this.

 

If this is a big issue for your organisation simply raise a feature request:

Re: Underscores in Polycom hostnames

Hi Steffan,

 

Thanks for your time.

 

I had read the FAQ on changing the hostname. That is where I began to wonder why Polycom was not RFC compliant. That particular FAQ supports that propsition that underscores are not acceptable in host names by reference to the older RFC 1035, but then goes on to give an example which uses them. That seems confusing at best.

 

Is there a way to include the MAC in the modfied hostname?
