nets(4)nets(4)NAMEnets - JOIN DHCP server database
DESCRIPTION
The nets file is employed by joind, the JOIN DHCP server, to tell it
which networks to administer and the ranges of IP addresses available
for dynamic assignment on each of those networks.
FORMAT
Blank lines and lines beginning with the number sign (#) are ignored.
Entries are separated from one another by newline characters. Entries
consist of three fields: the network number (expressed as an IP
address), the IP address or name of a host running joind, which dynami‐
cally configures clients on the network, and a range of available
addresses for dynamic allocation to hosts on the net. The range is
expressed as a pair of IP addresses separated with a dash (-). There
must be no whitespace separating the dash from the IP addresses.
Several servers may administer a single network, and a single server
may administer several networks. Each network-server pair may have sev‐
eral ranges of IP addresses available for dynamic allocation. The net‐
work and server IP addresses do not have to be repeated for each entry.
A line containing a single field is assumed to be an IP range with the
same server and network as the previous entry: a line of two fields is
assumed to be a server address and IP range with the same network as
the preceding entry.
The ranges of addresses served by each cooperating server must be dis‐
joint. This condition is checked by the server on startup.
