FlashProxy has added support for the SOCKS5 UDP ASSOCIATE command to its IPv6 Datacenter plan. The capability is live on existing credentials - customers on IPv6 Datacenter can route UDP traffic through their current SOCKS5 endpoint without provisioning a separate tunnel or switching protocols.

UDP ASSOCIATE is one of three commands defined in the SOCKS5 specification (RFC 1928), and it tells the proxy to open a relay for connectionless UDP packets rather than the TCP streams SOCKS5 handles by default. Most commercial proxy providers ship only the TCP path, because implementing a UDP relay at scale is operationally harder. For IPv6 Datacenter customers, this brings UDP transport to a plan built for high-volume operations against IPv6-reachable destinations - same endpoint, same credentials, expanded capability.
