QUIC Versions

Register the use of a QUIC version here to avoid collisions. Note: These values are all defined in big endian.
The (WIP) QUIC specification reserves 0x00000001 to 0x0000ffff for standardized versions of the protocol. Don't use these for experimental versions. There is plenty of space available on a first-come, first-served basis.
| Version | Owner | Notes |
|---|---|---|
| 0x00000000 | n/a | This value is reserved as invalid |
| 0x?a?a?a?a | IETF | Values meeting this pattern ((x&0x0f0f0f0f)==0x0a0a0a0a) are reserved for ensuring that version negotiation remains viable. Endpoints SHOULD use these values. Endpoints can expect that these versions will not be accepted by their peer. |
