Dear Colleagues, The IANA and the RIRs are working on an ongoing basis to verify and correct registration data of legacy address space to identify free space in these blocks. As a result of this work the RIPE NCC will begin allocating from 188/8 in future. The minimum allocation size for 188/8 has been set at /21. You may wish to adjust any filters you have in place accordingly.

These prefixes are: 188.0.0.0/16 188.0.0.0/21 188.0.0.0/24 They will all originate in AS12654.
