About
What this server hosts, how, and at what trade-offs.
oxmo.org is a single hand-administered server hosting four public sites: a forum open since 22 February 2002, a text-tools portal, IP address diagnostics, and a DNS and mail audit.
What “self-hosted” means here
One machine, in a room, with an operating system, a web server and a database kept up to date by hand. No shared hosting, no cloud, no platform between you and the service.
No external resources
No remote fonts, no CDN, no library loaded elsewhere, no analytics. The server’s content security policy forbids it, which makes the promise checkable in your browser’s network tab rather than merely stated.
The four sites
- www.forum.oxmo.org — the forum, online since 2002: over a million posts, 58,500 threads, eight sections.
- tools.oxmo.org — passwords, encoding, hashes, text diff, JSON.
- ip.oxmo.org — public address, operator, autonomous system, ping, traceroute, speed, CIDR maths.
- dns.oxmo.org — records, delegation, DNSSEC, SPF, DKIM, DMARC, MTA-STS.
Writing in
A question, something to report, a correction: the contact form lands straight in the mailbox of whoever runs the server.
