As there are no explicitly indicated limitations in the current
policy, we implemented this such that an organization can request
and be granted one /24 *per request*. The frequency of the anycast
requests however (from the same organization) is unlimited per our

While reading through the new proposal - we also interpret it such
that one /24 v4, one /48 v6 prefix and one ASN will be assigned with
*each* anycast request from the same organization, and there is no
limit on the number of times the same org can request such resources.
