These often resolve to multiple IP addresses, each of which may have different performance and connectivity characteristics. Since specific addresses or address families (IPv4 or IPv6) may be blocked, broken, or sub-optimal on a network, clients that attempt multiple connections in parallel have a higher chance of establishing a connection sooner. This document specifies requirements for algorithms that reduce this user-visible delay and provides an example algorithm.}, }
