--------------------------------------
Type: Technical
Reported by: Seymour J. Metz <[email-masked]>

Section: 5.6.  "ip4"

Original Text
-------------
  ip4-cidr-length  = "/" ("0" / %x31-39 0*1DIGIT) ; value range 0-32
  ip6-cidr-length  = "/" ("0" / %x31-39 0*2DIGIT) ; value range 0-128

Corrected Text
--------------
  ip4-cidr-length  = "/" (DIGIT / 
                          %x31-%x32 DIGIT /
                          %x33 %x30-%x32) ; value range 0-32

  ip6-cidr-length  = "/" ("0" /
                          %31-%39 0*1DIGIT /
                          "1" %30-%31 DIGIT /
                          "12" %30-%38) ; value range 0-128

Notes
-----
As written the ABNF matches ranges 0-99 and 0-999, not the ranges in the comments.

Note: I coded the ABNF the way that I did to avoid leading zeros.
