DHCPSD_ETHERS(8)

NAME
ethers - lookup IP addresses from the ethers(5) database.

DESCRIPTION
ethers will lookup a line in ethers(5), matching the ethernet address to the chaddr field in the DHCP message for messages with have a htype of 1 and a hlen of 6.

If the matched line does not have an IP address then it is assumed to be a hostname and is looked up using getaddrinfo(3) and the first IP address returned is the one used.

If the client asks for a hostname in the parameter request list option and we have matched a hostname to the ethernet address then the hostname is added to the DHCP reply for OFFER and ACK messages.

Any IP address returned overrides any that the client requested.
