Which IPv4 address block is reserved for documentation and examples?

Explanation:
Documentation and example blocks are set aside so you can show network addresses without risking real routes or allocations. This is defined in RFC 5737, which designates three IPv4 blocks for documentation and examples: 192.0.2.0/24, 198.51.100.0/24, and 203.0.113.0/24. These ranges are reserved and not assigned for actual use on the public Internet. The block 198.18.0.0/15, by contrast, is reserved for benchmarking inter-network interconnect tests, not for documentation. So, among the options, the blocks suitable for documentation examples are the ones in the 192.0.2.0/24, 198.51.100.0/24, and 203.0.113.0/24 ranges (with 192.0.2.0/24 often cited as the canonical example).
