Options for 240.0.0.0/4

• Make Space Unicast Public
• Makes it potentially available sometime down the
  line
• Make Space Unicast Private
• Lets consenting adults use space(draft-wilson-c
  lasse-01.txt)
• Split space up in some way
• Do Nothing

4
Our Approach

• We dont yet know or agree on how address space
  should be used, except
• Someone should use it
• The Future begins tomorrow Make code changes
  NOW and lets figure out whether its public or
  private in the coming months
• This is what draft-fuller-240space-00.txt says

5
There is some running code

• Vince made the changes to Linux
• 5 files, removing a few lines each
• Could easily be a binary patch
• FreeBSD and MacOSX (mostly) work
• One minor change if system is router
• More code needed (in a lot of places) this will
  take time.
