[Feature Request] (Sub)Domain / Substring wildcard matching for IP/Host Switches

[I-Knight-I]

Quick summary

PlayStation Network (like many others) uses a lot of different domains that are otherwise very similar except for a minor difference. It'd be useful to be able to redirect these with a wildcard (*)

Details

An example might be:

• scea.playstation.net
• scee.playstation.net
• scej.playstation.net

Which would be written as: scea.playstation.net=0.0.0.0&&scee.playstation.net=0.0.0.0&&scej.playstation.net=0.0.0.0

It'd be useful to be able to redirect each of these with a wildcard rather than having to swap each one. So those three switches will simply become: *.playstation.net=0.0.0.0 -- which is much simpler and cleaner.

Whilst that covers subdomains, it'd also be useful to have - if possible - string-matching wildcards. For example, you might want to redirect every domain with any substring at a certain point but not all subdomains:

• test-one.playstation.net <---- We want to reroute this
• test-two.playstation.net <---- We want to reroute this
• scea.playstation.net <---- We do NOT want to reroute this

So a valid wildcard for this could be:

• test-*.playstation.net

Whereas a subdomain wildcard (*.playstation.net) would switch all three; including the one we don't want to reroute.
In the case of substring wildcards, subdomains are implicitly covered.

1. Please describe, what part of RPCS3 would be affected by your feature:

• Networking

2. Please tell us, why your feature is important to RPCS3.

• Ease of use
• Simpler than current implementation
• Cleaner than current implementation
• Should be relatively simple to implement

3. Please attach screenshots of the feature implemented in other projects.

Wildcard matching is a very popular and accepted tool across the entire tech industry:
