Is Dhcp option 53 mandatory in Dhcp offer?
I'm trying to find out whether option 53 in DHCP offer is mandatory or not.
I've found this short snippet:
in book but I'm looking for any confirmation in rfc. I've checked this one but in section about option 53 there is no word of whether it is mandatory.
Do you have any suggestions about where I can find the answer?
Solution
I've found the answer in: https://datatracker.ietf.org/doc/html/rfc2131#section-3
Several options have been defined so far. One particular option - the "DHCP message type" option - must be included in every DHCP message. This option defines the "type" of the DHCP message. Additional options may be allowed, required, or not allowed, depending on the DHCP message type.
