For the others here that didn't know what that is and are 
curious.  I couldn't take it and just had to know... :)

https://tools.ietf.org/html/rfc4786

Catchment:  in physical geography, an area drained by a river, also
      known as a drainage basin.  By analogy, as used in this document,
      the topological region of a network within which packets directed
      at an Anycast Address are routed to one particular node.
