Hi everyone

 

I have  a doubt about these concepts. Fixed is done with mac address or client ID with IP but reserved is confuse for me.

What's the main use of Reservation, scenarios and the difference with Fixed.

Now these reserved IP can be used within the range or out the range?

In the case of Fixed address also can be used out of the range?

Thank you for you suggestions

Hello There,

 

To keep it simple, "DHCP Reservations" are IP addresses binded to MAC address 00:00:00:00:00:00 which means that this IP address will NEVER be leased out to a client & is for future purposes. So unless you decide to change your mind & add these ones to a DHCP pool or bind a MAC address with each of them etc, they stay always as Reserved.

 

On the other hand DHCP Fixed addresses are something that can be leased out immediately when a client with the defined MAC/Client Id approaches the server for a lease. You can have fixed addresses within or outside a scope. 

 

Best regards,

Mohammed Alman
