There is an ongoing pattern of OmanTel hijacking IP space and =
advertising it to many of their peers (but not transits).
here=E2=80=99s the most recent announcement. This could be mitigated in =
a few days, such as filtering your peers on a prefix basis, or at =
minimum rejecting the private ASN space, eg: 64512-65535, as well as the =
4 byte variant range: 4200000000-4294967294
Please take a moment and update your AS_PATH filters to minimize the =
pollution you accept or propagate.
