Outside the concept of the `Subnet` object, most everything else in Arcus is auxiliary and exists only in support of making this once facet work.

 A `Subnet` may be instantiated in several ways:
 
 To the most common ways to create a subnet is to construct it via a high and low `IPAddress` call the constructor `Subnet(IPAddress primary,  IPAddress secondary)` This construct the smallest possible subnet that would contain both IP addresses typically the address specified are the Network and Broadcast addresses (lower and higher bounds) but this is not necessary. Addresses *MUST* be the same address family (either Internetwork or InternetworkV6)
 
 It is also possible to create a `Subnet` from an `IPAddress` and an `integer` based *route prefix*. Eg: `Subnet(IPAddress ipAddress, int routingPrefix)`
 
-Likewise it may be desired to statically parse a subnet string with `Subnet. Parse(string input)` or it’s safe equivalent of ` bool Subnet.TryParse(string input,  out Subnet subnet)`. For example, one could safely parse the `string` "192.168.1.0/16" via
