The article explains why IP certs are uncommon, how subscribers can use them (including DoH and remote access), and the steps to obtain them (currently in staging with general availability planned for 2025). It also highlights policy constraints (no DNS-01 challenge) and practical considerations for clients and hosting environments.

jq is a lightweight, portable C-based command-line tool for parsing, filtering, and transforming JSON data, designed as a fast, zero-dependency alternative to traditional text-processing utilities. It provides multiple installation paths (prebuilt binaries, Docker, source builds) and an active ecosystem with documentation, community support, and ongoing development. The project emphasizes a robust, extensible approach to JSON manipulation with a permissive MIT license.
