WebJul 19, 2024 · The longest prefix/smallest subnet for IPv4 that can be announced on public BGP is /24 = 256 IP addresses. Note that each announcement likely ends up in the global routing table. Limiting the amount of fragmentation (somewhat) protects that table from exploding. Still, it holds close to 900,000 IPv4 prefixes (out of 16 million theoretically).
