I'm using .NET 7. Given I have an instance of type 'Uri'. What check do I need to do in order to make sure the address doesn't point to a local network?

hello! i'm here to help you with your question. to check if a `uri` object points to a local network, you can perform the following check:
1. check if the `uri` starts with "http://" or "https://": if the `uri` starts with either of these prefixes, it is likely to be a remote address.
2. check if the `uri` contains a colon (:) or a backslash (/) symbol: these symbols are typically used to separate the authority part of a `uri` from the path and query parts. if the `uri` contains one of these symbols, it is likely to be a remote address.
3. check the authority part of the `uri`: the authority part of a `uri` is the portion before the first colon or backslash. if the authority part contains a domain name or an ip address, it is likely to be a remote address. you can use the `uri.get effetiveport()` method to check if the authority part contains a port number. if it does, it is likely to be a remote address.
4. use the `uri.isloopback()` method: this method returns a `bool` value indicating whether the `uri` is a loopback `uri`. a loopback `uri` is a `uri` that has the same ip address as the machine it is running on. if the `uri.isloopback()` method returns `true`, it is likely to be a local address.
by performing these checks, you can determine if a `uri` points to a local network or not. if you have any doubts or are unsure about the answer, please let me know and i'll do my best to help.
