Why 4271 is special

It is the protocol by which the internet's networks tell each other what they can reach, and a single wrong announcement can misdirect a country's traffic.

1 × 4,096 + 0 × 256 + a × 16 + f × 1 = 4,271

Read as powers of two: 4,096 + 128 + 32 + 8 + 4 + 2 + 1 = 4,271.

4 × 1,000 + 2 × 100 + 7 × 10 + 1 × 1 = 4,271. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.

Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Technology & computing

  • RFC 4271 specifies BGP-4, a path-vector protocol exchanging reachability between autonomous systems. It trusts announcements by default, which is why route leaks and hijacks propagate quickly.
