function Get-NetworkTopology { <# .SYNOPSIS Used to build a text or HTML based visual topology of all related child networks .DESCRIPTION This function is used to build a text or HTML based visual topology of all related child networks, based on a parent IP Space, Address Block, Subnet or Range. .PARAMETER Object The IP Space, Address Block, Subnet or Range to build a visual topology from. This parameter expects pipeline input. .PARAMETER IncludeSubnets Determines whether subnet objects are included in the topology output. This may make the results take longer if there are a large number of subnet objects. .PARAMETER IncludeRanges Determines whether range objects are included in the topology output. This may make the results take longer if there are a large number of range objects. .PARAMETER IncludeAddresses Determines whether address objects are included in the topology output. This will make the results take longer if there are a large number of address objects. .PARAMETER HTML Using the -HTML switch will open a HTML based Network Topology viewer .EXAMPLE PS> Get-B1Space mcox-ipspace | Get-NetworkTopology -HTML -IncludeSubnets -IncludeRanges .EXAMPLE PS> Get-B1Space my-ipspace | Get-NetworkTopology -IncludeSubnets -IncludeAddresses -IncludeRanges Building Network Topology.
