DHCP disabled?

In the first paragraph (Overview) the explanation for manual DHCP begins with: 

"The DHCP server is disabled and"

Which is clearly wrong and should be deleted.

Of course the DHCP-server is enabled. I assume the person who wrote this wanted to say, that the DHCP-server is not giving leases to clients which are not listed in the DHCP-configuration with a MAC-address and an according IP-address. — Preceding unsigned comment added by 212.149.48.42 (talk) 09:22, 11 August 2016 (UTC)[reply]

Client ID is starting to replace MAC address

And this article is still assuming that the client is presenting a MAC address. I've pushed in some qualifications, but haven't provided any RFC's or references.

Most of the documentation on the web still assumes that clients will be presenting either EUI-48 or EUI-64 identifiers, but that's no longer the case: current Linux distributions (including Ubuntu) are presenting to DHCP machine ID's that do not include hardware-level identifiers at all.

The reason described for this change is that a machine with wired and wireless connections should by default present and acquire the same identification on both channels. This is not true if the hardware-level id's are bound to application-level ids, which happens if hardware-level id's are bound to IP address.

I notice that a comment about this was made on the talk page in 2007, so the technology is not new, but it's becoming more widespread — Preceding unsigned comment added by 203.206.162.148 (talk) 01:59, 6 September 2018 (UTC)[reply]

DHCPACK destination address

The example DHCPACK message lists 192.168.1.100 as its destination address in the IP section which contradicts teaching literature (Kurose & Ross: Computer Networking: A Top-Down Approach, where DHCP ACK is still being broadcasted) and seems to be at odds with RFC2131, Section 3.2.3. The example might still be correct, but if so an explanation why the offered IP address may already be used would be helpful.

Hard to read sentence in section "DHCP relaying"

The following sentence is really hard to read:

In this case, a DHCP client that has not yet acquired an IP address cannot communicate directly with the DHCP server using IP routing, because it does not have a routable IP address, does not know the link layer address of a router and does not know the IP address of the DHCP server.
