The following errata report has been submitted for RFC2131,
"Dynamic Host Configuration Protocol".

--------------------------------------
You may review the report below and at:
https://www.rfc-editor.org/errata/eid7776

--------------------------------------
Type: Technical
Reported by: Imrane <sahsah.imrane@gmail.com>

Section: 4.3.1

Original Text
-------------
In the page 29 (if you were reading on a PDF),
section "4.3.1 DHCPDISCOVER message"
"table 3: Fields and options used by DHCP server",
on the "options" list, the "Client identifier" option, 
it says "MUST NOT" for both DHCPOFFER and DHCPACK, however on DHCPNAK it says "MAY".

Corrected Text
--------------
"Client Identifier" should be a "MUST NOT" for the DHCPNAK as well. 

Notes
-----
It seems that the field should only be used by a client and never by a server, and if that's true for the OFFER and ACK, then it should be even more correct for the NAK.

"Vendor class identifier" has a MAY for all three messages, so maybe it was a typo in the previous option because of the repetitive input in the next one.

Instructions:
-------------
This erratum is currently posted as "Reported". (If it is spam, it 
will be removed shortly by the RFC Production Center.) Please
