Fixing this required the removal of the code that attempted to detect virtual interfaces. Not wanting to remove functionality, but not able to keep the code in place, I implemented a work around solution (see 4 below).
Whilst in the area, I also fixed a few minor bugs i encountered (1, 5, 6 below) and stopped SSDP messages from going out on non-LAN interfaces (3)
All these changes are related.
Changes
1 IsInPrivateAddressSpace - improved subnet code checking
2 interfaces with no gateway were being excluded from SSDP blasts
3 filtered SSDP blasts from not LAN addresses as defined on the network page.
4 removed #986 mod - as this was part of the issue of #2986. Interfaces can be excluded from the LAN by putting the LAN address in brackets. eg. [10.1.1.1] will exclude an interface with ip address 10.1.1.1 from SSDP
5 fixed a problem where an invalid LAN address causing the SSDP to crash
6 corrected local link filter (FilterIPAddress) to filter on 169.254. addresses

This will be the right way for multiple interfaces, or the client will
receive all devices message with different IP addresses and could not
detect which one could access.
And provide one option DlnaOptions.SendOnlyMatchedHost to fallback to old
behaviour if this commit missed something.
Some VPN like ZerotierOne owns IP address but no gateway, and there is no
good idea in NetworkManager.GetIPsDefault() to filter such virtual interfaces,
so just provide one option to let user decide it.
Add Argument*Exceptions now use proper nameof operators.
Added exception messages to quite a few Argument*Exceptions.
Fixed rethorwing to be proper syntax.
Added a ton of null checkes. (This is only a start, there are about 500 places that need proper null handling)
Added some TODOs to log certain exceptions.
Fix sln again.
Fixed all AssemblyInfo's and added proper copyright (where I could find them)
We live in *current year*.
Fixed the use of braces.
Fixed a ton of properties, and made a fair amount of functions static that should be and can be static.
Made more Methods that should be static static.
You can now use static to find bad functions!
Removed unused variable. And added one more proper XML comment.
