Creating a Primary Forward Zone

To create a domain (or forward zone) and include all forward mapping (the “A” records) for the domain, follow these steps:

Step 1 Create a domain and include all forward mapping (the “A” records) by entering the zone command with the create option:

nrcmd> zone the.net create primary file=the.net.zone.txt

To create new subnets by using the CLI, import a BIND zone definition file, which can be edited by using an ASCI text editor. The following example shows an edited BIND file.

@	IN	SOA	onionring.the.net. netadmin.the.net. (
		2000071600		; serial number
		3600		; Refresh 1 hours
		1800		; Retry 30 minutes
		86400		; Expire 24 hours
		86400		; TTL 24 hours
		)
IN	NS	onionring.the.net.
doc-rtr58-01	IN	A	172.21.101.20
doc-rtr54-01	IN	A	172.21.101.21
doc-rtr53-01	IN	A	172.21.101.22
doc-rtr53-05	IN	A	172.21.101.23
doc-3810a-01	IN	A	172.21.10.14
doc-3810d-01	IN	A	172.21.10.15
doc-ubr7246-01	IN	A	172.21.10.16
doc-switch-02	IN	A	172.21.10.17

Step 2 Verify that the primary zone was created by entering the zone command with the listRR option:

nrcmd> zone the.net listRR
100 Ok

netadmin.the.net.0
@	IN	NS	onionring.the.net.

doc-rtr53-01	IN	A	172.21.101.22
doc-rtr53-05	IN	A	172.21.101.23

Creating an IP Tracker Web Page

An IP tracker web page:

•Provides web access to the IP database that is managed by Cisco Network Registrar.

•Retrieves current IP address block assignments from a DNS server.

•Uses two CGI scripts to provide a web-enabled look into DNS for each zone.
