  "whatItIs": "IANA registers 2492 as groove, assigned to Ray Ozzie — Groove Networks' peer-to-peer workspace client, which Microsoft acquired and shipped as Office Groove 2007, renamed SharePoint Workspace 2010, and then dropped from Office 2013 in favour of OneDrive for Business. Groove clients used 2492 for direct peer traffic when they could reach each other, falling back to HTTP/HTTPS otherwise. Nothing currently supported listens here, so a live 2492 is either a very old Office install or an unrelated program on a free port.",
