DHCP Details You Didn’t Know
If you’ve been a networking engineer (or a sysadmin) for a few years, you must be pretty familiar with DHCP and might think you know everything there is to know about this venerable protocol. So did I… until I read the article by Chris Marget in which he answers two interesting questions:
- How does the DHCP server (or relay) send DHCP offer to the client that doesn’t have an IP address (and doesn’t respond to ARP)?
- How does the DHCP client receive the DHCP responses if it doesn’t have an IP address?
Sometimes I wish I could speak and someone would listen.
Let me ask again about DHCP with static binding on IOS router.
I have origin file for the dhcp pool and I badly want to have same static IP addresses for every host no matter what we boot: windows, linux or PXE. Do You have any solution for this? How to force an IOS to treat hw address as client-id when no client-id is passed by the requesting machine?
