{
<#
.Synopsis
    Gets which Boundary an IP Address belongs to.
.DESCRIPTION

    IPAddress     : 10.1.1.110
    BoundaryFlags : 0
    BoundaryID    : 16778243
    BoundaryType  : 3
    DisplayName   : testBoundary2

.EXAMPLE
    Get-IPAddressBoundary -SiteServer dexsccm -IPAddress 10.1.1.99 


    IPAddress     : 10.1.1.99
    BoundaryFlags : 0
    BoundaryID    : 16778242
    BoundaryType  : 3
    DisplayName   : testBoundary1

    IPAddress     : 10.1.1.99
    BoundaryFlags : 0
    BoundaryID    : 16778245
    BoundaryType  : 3
    DisplayName   : Overlapping Boundary
