Detailed instructions

1. Set the Count field to the number of config blocks you need for your test or documentation task.
2. Open the Config Type dropdown and select the format that matches your use case: host, interface, firewall rule, or VPN peer.
3. Click Generate to produce all config blocks at once in the output panel below.
4. Review the output to confirm the field structure matches your expected schema, then copy individual blocks or the full output.
5. Paste the configs into your test fixture, documentation template, or seed script as needed.

Use Cases

• •Seeding a CMDB or network inventory demo with realistic host and subnet records
• •Unit-testing a firewall rule parser against varied protocol, port, and action combinations
• •Populating Ansible inventory files with dummy host configs before real devices are provisioned
• •Building VPN peer entries for integration tests in a Terraform or Pulumi staging environment
• •Creating onboarding lab configs for new network engineers without exposing live topology

Tips

• →Generate firewall rule configs in batches of 20+ to get enough field variation for thorough parser edge-case testing.
• →If you need strictly RFC 1918 private addresses, filter the output for 10.x, 172.16-31.x, or 192.168.x ranges before use.
• →Combine host and interface outputs to build a two-layer inventory: hosts as the device layer and interfaces as the port layer.
• →For VPN peer configs, generate at least two sets and pair them manually to simulate realistic tunnel endpoint relationships.
• →Use the output as seed data in factories or fixtures files so your test suite always has deterministic-looking but varied network data.
• →When demoing a network UI, generate configs across all types and mix them in your demo dataset to show how the interface handles diverse record formats.
