This draft discusses the use of two DNS record types for storing BGP
routing information in the reverse DNS. The RLOCK record allows
prefix owners to indicate whether the DNS is being used to publish
routing data. The SRO record allows operators to indicate whether an
IPv4 or IPv6 prefix ought to appear in global routing tables and
identifies authorized origin Autonomous System Number(s) for that
prefix. The resulting published data can be used in a variety of
contexts from routing security to address ownership.
