DHCP ranges seperate for IP Phones and PCs?
-
Trying to go through my inventory through
and wanting to clean things up in there. Was wondering if creating two ranges for phone and PCs would be a good idea. Not sure of the benefits or bad things about it but what better place to ask 
-
I think what your asking for is VLANS, otherwise how will you differentiate between phone and PC. you can use MAC address IP reservation, but thats it.
-
You can create separate ranges, but there isn't going to be a benefit for doing so. If your scope didn't have enough room for your systems and phones I could see doing this, but why not just go to a /22?
-
Using multiple ranges can actually improve performance of the scans because it doesn't have to load 2million IP addresses.
-
Yes, multiple ranges can improve scanning.

If
is working right now, adding an additional range will not help if you already have them in the same network. -

I have VLANs already. 1 for Wired, 1 for Secured WiFi (Profs and Staff), and 1 for Students and Guests.

Why split your phones off into their own subnet?

That's the reason for the post. Is there a benefit?

What size is your subnet now?

Also believe me , do not enable
on a VoIP VLAN as it will not find the phones since they cannot scan port 5060 and it will just fill your network with scans to every single possible IP on that network. -

/16
That is not what I scan through
though -

And you can put them on different schedules.

Oh, that's a problem. No network should be that large. /20 maybe, /21 sure. But /16 is so many times bigger than that.

Not to splitting, no. But to not scanning them, yes.

What are you using the
scan to provide? -
@wls-itguy are you actually trying to make a separate subnet or just organize them in a section of you existing subnet?

I'd be all for a separate range. But see no point in what was mentioned here for a separate VLAN.

What are you using the
