    abstract =  {To reduce the likelihood of conflict and confusion when relating documented examples to deployed systems, an IPv6 unicast address prefix is reserved for use in examples in RFCs, books, documentation, and the like. This document adds an additional prefix to the existing reserved IPv6 prefixes, 2001:db8::/32. This document describes the use of the IPv6 address prefix 3ffe::/16 (formerly 6bone) as a reserved prefix for use in documentation.},
