``POST``
========
Creates a new federation resolver.

:Auth. Required: Yes
:Roles Required: "admin"
:Response Type:  Object

Request Structure
-----------------
:ipAddress: The IP address of the resolver - may be IPv4 or IPv6
:typeId:    The integral, unique identifier of the :term:`Type` of resolver being created

	.. caution:: This field should only ever be an identifier for one of the :term:`Types` "RESOLVE4" or "RESOLVE6", but there is **no protection for this built into Traffic Ops** and therefore **any valid** :term:`Type` **identifier will be silently accepted by Traffic Ops** and so care should be taken to ensure that these :term:`Types` are properly identified. If any :term:`Type` besides "RESOLVE4" or "RESOLVE6" is identified, the resulting resolver *will* **not** *work*.

	.. seealso:: :ref:`to-api-types` is the endpoint that can be used to determine the identifier for various :term:`Types`
