HI Group

I have following setup

R1====|
            |
            |==== R3
            |
R2====

My DHCP server is running on R3 .
I want say 172.16.12.2 to be assigned to R1 and 172.16.12.12 to be
assigned to R2.

I am able to do this using host and client identifier .

R3(config)#do sh run | sec dhcp
ip dhcp pool TEST
   host 172.16.12.2 255.255.0.0
   client-identifier
0063.6973.636f.2d30.3031.632e.3538.6261.2e66.6532.302d.4661.302f.30
ip dhcp pool TEST1
   host 172.16.12.12 255.255.0.0
   client-identifier
0063.6973.636f.2d30.3031.612e.6132.6166.2e36.3830.382d.4661.302f.30
R3(config)#

My query is is there a way to CALCULATE the client identifier ?

I got the above by simply creating a DHCP pool on R3(server) in this
case to start off and enabling DHCP debugs .
As address is assigned by server to clients .. we do get what address
is assigned to what client

But is there a way we can somehow calculate this ?

Thnx
