[rrg] NANOG44 session on current IP address challenges

[Tony Li]

|There's no doubt Jon felt strongly about this. I'm not sure whether he
|or Lixia was the originator of the following words in RFC 1958:
|
|   3.11 Circular dependencies must be avoided.
|
|      For example, routing must not depend on look-ups in the Domain
|      Name System (DNS), since the updating of DNS servers depends on
|      successful routing.
|
|It might have been Lixia, because the point was explicit in her report
|of the plenary discussion at IETF 33:
|
|     "  In addition to the need
|for autoconfiguration on tools at low levels, renumbering requires
|changes to high-level protocols.  It also puts further reliance on the
|DNS system to keep up-to-date address binding.  To avoid circular
|dependency, DNS servers themselves will require special treatment,
|such as provider-independent addresses, assured connectivity, issues
|that are yet to be explored.  "


I fully understand the (blindingly obvious) concern about circular
dependencies with DNS.  I also understand the issues with overloading DNS (a
naming system) and turning it into a Internet database system.  Are there
concerns *past* those points about leveraging DNS?
