Where 9200 fits
Why 9200 is special
Elasticsearch shipped for years with no authentication and bound to every network interface, and exposed 9200 became one of the largest sources of publicised data leaks in the late 2010s. The defaults changed; the exposed instances did not all go away.

9 × 1,000 + 2 × 100 = 9,200. 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.

Elasticsearch stores the data and Kibana displays it. Early versions of both shipped without authentication, and an exposed dashboard leaks exactly what an exposed database does.

Technology & computing
Elasticsearch long shipped with no authentication and listened on every interface, and exposed port 9200 became one of the largest single sources of publicised data leaks in the late 2010s. The defaults were changed; the already-exposed instances largely were not.
