table

.1.3.6.1.4.1.9.10.102.1.4.1 · 1 row entry · 6 columns

Open in standard view

A list of shared networks that are configured in the server.
A shared network is the logical aggregation of one or more 
subnets that share a common network segment (e.g., multi-
tapped coaxial cable, wiring hub, or switch).  This table is 
present ONLY for those servers that organize the ranges of 
addresses available for assignment where a higher-level 
grouping (i.e., the 'shared' network) exists above ranges and 
subnets.

An optional list of addresses that are known by this server.
The list MUST contain addresses that have not expired.  The 
list MUST NOT contain addresses that have never been assigned 
by the server UNLESS the lease is pre-configured in the server 
(e.g., a static lease for a host).  Expired leases MAY appear 
during the time they are 'remembered' by the server for 
subsequent assignment to the same host.
