DHCP ranges seperate for IP Phones and PCs?

Using multiple ranges can actually improve performance of the scans because it doesn't have to load 2million IP addresses.
And you can put them on different schedules.

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?
/16
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
scan to provide?PC info and Network info. Ticketing as well. I know SodiumSuite does all that as well.

If I could organize them within the subnet so 172.16.1.x/16 is the range and if all phones (FreePBX system) could get 172.16.5.x and all PCs goes 172.16.1.x range that would be great. I don't think that is possible though.

It does indeed.

As other conversations have been had with you on this it doesn't do Network switches or phones though, correct?
If not, will that be a feature that will happen?
-
@wls-itguy Does the scanner from
inventory these systems?I thought SodiumSuite does but I'd defer that to @Sodium to answer.

No, does not scan devices on which it cannot be installed.

I guess with having PRTG that really wouldn't be needed.

Correct, you'd already be covered there.

You can setup DHCP reservations for all the phones easily enough. It is manual, but not hard.
Assuming windows DHCP
dhcp server \\172.16.1.?? scope 172.16.1.0 add reservedip 172.16.5.X MACADDRES "ext101" "" "BOTH"And repeat for all the phones.

This could very easily be drafted into an excel doc as well so each line doesn't need to be manually typed again and again.
-
Windows DHCP server scopes can do some stuff with MAC address filtering too, but you still have to explicitly define everything, so I prefer to just use DHCP reservations.

here it he powershell method.
Add-DhcpServerv4Reservation -ScopeId 10.10.10.0 -IPAddress 10.10.10.8 -ClientId "F0-DE-F1-7A-00-5E" -Description "Reservation for Printer"`
