  "whatItIs": "IANA lists 8982–8988 as Unassigned, so 8987 has no registration and no protocol you can assume from the number alone. It is close enough to 8983 — Apache Solr's default — that it turns up on the same hosts as an extra or second-instance port, but that is a local choice, not a convention. Look at the process, not the number.",
