networks
The networks map is the the abbreviated name for the networks.byaddr map. The derived maps are networks.byname and networks.byaddr. In most cases, the networks map is created from the /etc/networks file. A typical line looks like this:
network_name network_address [alias1,...] # comment
For example:
arpa 10 arpanet intra_1 123.45.67.89 intranet # headquarters sf_site 171.22.0.0 sf1 # san francisco satellite
For the networks.byname map, entries are defined like this:
- Key is the network name: intranet
- Value is the network address and any aliases defined for the network: intranet 171.22.0.0 intra
For the networks.byaddr map, entries are defined like this:
- Key is the network address: 171.22.0.0
- Value is the network name and any aliases defined for the network: intranet 171.22.0.0 intra
If you create a networks map in Active Directory, you must include the key as part of the value. For example:
- Key: intranet
- Value: intranet 171.22.0.0 intra
- Comment: The value includes the network name and address
