- Can I have more than one?
- Click the button as often as you want.
- What do I do if I don't want it anymore?
- Nothing. Just stop using it.
- What if too many people click and they run out?
- Seems unlikely. The number just keeps getting bigger — there is no upper bound.
- Why don't I have to register an account or provide details?
- Because there's no need. OIDs aren't that precious.
- Is the OID I get real?
- Yes. The base 1.3.6.1.4.1.54392.5 is a Private Enterprise Number registered with IANA, and your number lives underneath it.
- Can I delegate sub-OIDs under mine?
- Yes — that's the whole point of an OID. If you're given 1.3.6.1.4.1.54392.5.42, you have the authority for everything under it: 1.3.6.1.4.1.54392.5.42.1, 1.3.6.1.4.1.54392.5.42.2.7, and so on.
- What can I use it for?
- Anywhere an OID is required — SNMP MIBs, X.509 certificate extensions, LDAP schemas, ASN.1 modules, your own protocol identifiers. If you don't already know you need one, you probably don't.
- Will FreeOid still be here next year?
- The current version is intentionally simple — a tiny Go binary on a server I run — so the cost of keeping it alive is essentially zero. The previous incarnation lived for six years on free hosting before the host shut down. Worst case, the OIDs stay valid forever even if the website doesn't.
