11 y 12 Noviembre. México DF LACNIC III Inverse Resolution - proposal Frederico A C Neves

11 y 12 Noviembre. México DF LACNIC III Inverse Resolution - proposal in-addr.arpa zone Used for inverse resolution –Sample reverse resolution > in-addr.arpa. IN PTR –Sample direct resolution -> IN A Delegation schema of sub-zones limited by the 8 bits boundary format of representation

11 y 12 Noviembre. México DF LACNIC III Inverse Resolution - proposal Delegation base on allocated prefix size /16 or shorter –Multiples delegations at the 16th bit boundary Sample 200.2/15 –2 zones in-addr.arpa and in-addr.arpa /17 to /24 –Multiples delegations at the 24th bit boundary Sample /20 –16 zones from in-addr.arpa to in-addr.arpa /25 or longer –Recommended the use of BCP20

11 y 12 Noviembre. México DF LACNIC III Inverse Resolution - proposal Discussion / Consensus Reach ?

11 y 12 Noviembre. México DF LACNIC III Inverse Resolution - proposal Lame delegation control Motivated by the side effects caused by some resolver implementations that impose higher load at upper levels of the delegation (notably /8 delegated servers for.in-addr.arpa). Already monitoring reverse lame delegations. Proposal should be addressed by a new working group at the mailing list. Volunteers ? Possible questions for the mailing list –What is the criteria to classify a multi zone delegation as lame ? –What should be the procedure when classified ?
