How does a DHCP server determine an IP address?
The DHCP server assumes that the address was assigned by another DHCP server on the same segment if it’s not from its own pool. If the address fails the subnet mask/IP address check, the DHCP server checks to see if it came from a Superscope, if one is defined. If not, the server responds to the DHCPRequest with a NACK packet.
What kind of device picks up the wrong IP address?
I have an iPhone 6. It is the only device in the entire house that picks up the wrong IP address. Other iPhones, non-Apple devices, laptops, desktops, etc. are fine. But my phone is always assigned a link-local IP-address (169.254/16) instead of a private IP-address (192.168/16).
What happens if the DHCP address is not on the same subnet?
If it originated from the local segment, the DHCP server compares the requested address to the IP address and subnet mask belonging to the local interface that received the request. If the address appears to be on the same subnet, the DHCP server will remain silent even if the address isn’t in the range of its pool of addresses.
