Invalid IPAddress throws and stops. about hostsfilemanagement

[Stephanevg]

In my eyes, if it is already in the HostsFile, then we should throw an exception. (or minimal would be a warning message.

If it is creating an entry using one of the constructors of [HostsEntry], It should throw an error, definitley.
This functionality is actually already in the this class if I am not mistaken. By casting it to [IpAddress] it will not allow you to set an invalid Ip address as showed below:

Is that what you had in mind?

I added two new tests here -> 22500f9 That actually tests that it correctly throws an error when a wrong type of IP address is passed to the constructor of [HostsEntry].

Good one! The host file can still be edited manually with invalid data. You could also use it to parse if the Hosts file is valid and re-mediate any issues found.

I'll close this issue since the error handling on the IPAddress type is already handled through the Casting to [IpAddress].
