## Worked Examples

Worked examples of this endpoint, each on its own page with the exact request and its response: [Reverse IP Examples](/reference/discovery/reverse-ip/examples/).

- [Domains on One IP Address](/reference/discovery/reverse-ip/examples/ip-address/): The domains whose A record points to 104.26.10.21: 190 on the day of capture, each with the address in `dns.a.ip_addresses`.
- [Domains in the Same /24 Network](/reference/discovery/reverse-ip/examples/mask-24/): Widens the lookup to the /24 network of 104.26.10.21 (104.26.10.0–104.26.10.255): 43,349 domains instead of 190.
- [Including Subdomains](/reference/discovery/reverse-ip/examples/include-subdomains/): Adds subdomains that point to 104.26.10.21 to the registrable domains: 3,003 records instead of 190.
