Can some one explain this DHCP config to me?

[Guest Noob]

1 DHCP server (win2003)

2 scopes

10.x.x.x

192.x.x.x

 

I have IP phones that get the 192 address and the PC's get the 10

address. Both are set to use DHCP. Both are connected to the same

switches/network and not going through any router.

 

How is this working?

More info

 

My switches do have vlans configured for these ranges.

 

So, this is segmenting the network and the phone is using the "ip

phone (155) and vlan option (156)".

 

I think I figgured out how it is connfigured. can anyone shed more

light on this for me?

What is the question?

 

If the question is how does the server know which scope to allocate,

then it can do it by MAC.

VLAN's aren't necessary for routing, but may be a security enhancement

or it may allow lower latency for the VoIP.

The question is:

Why are the systems not picking up the 192 address and the phones do

not pick up the 128?

 

I am just trying to under stand DHCP a bit more.
