Reserve IP based on DHCP Option 61 insted of MAC Address

tg flag

a DHCP client is sending a discovery packet with option 61. Now the Windows server 2019 /2022 needs to respond with the offer based on the DHCP reservation, reservation is registered based on option 61 value. However Serve is not generating offers based on my reservation.

  • I won't have mac address, in this scenario.

This is due to the reservation is not configured correctly. I use win server 2022.

DHCP Discovery Packet DHCP Discovery

Add reservation dialog DHCP Reservation

The string value is not accepted, I get the below error DHCP Reservation Error

Either Powershell code did not make any difference

Add-DhcpServerv4Reservation -ScopeId $Scope.ScopeId -IPAddress $IPAddress -ClientId $ClientIdWithPrefix -Type Dhcp

Expecting help, on How to configure DHCP reservation based on IP address v4 and Option 61. Thanks in advance.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
