VersionNegotiationPacket class

Version negotiation packet sent when a peer doesn't support the requested version.

When a server receives an Initial packet with an unknown version, it replies with a Version Negotiation packet containing a list of supported versions. This packet has version 0x00000000 and no packet number.
