According to RFC 5737 the following blocks of IP addresses are recommended for use in documentation and examples:
- 192.0.2.0/24 (TEST-NET-1)
- 198.51.100.0/24 (TEST-NET-2)
- 203.0.113.0/24 (TEST-NET-3)
Addresses within the TEST-NET-1, TEST-NET-2, and TEST-NET-3 blocks SHOULD NOT appear on the public Internet and are used without any coordination with IANA or an Internet registry. Network operators SHOULD add these address blocks to the list of non-routeable address spaces, and if packet filters are deployed, then this address block SHOULD be added to packet filters.
If you happen to come accross the other blocks of IP addresses in my examples, know that I didn’t know it before.By privilege15
