K14800: Order of precedence for virtual server matching (11.3.0 and later)
Starting in BIG-IP 11.3.0, you can configure source addresses from which virtual servers accept traffic. The BIG-IP system uses the destination address, source address, and service port configuration to determine the order of precedence applied to new inbound connections. When a connection matches multiple virtual servers, the BIG-IP system uses an algorithm that places virtual server precedence in the following order:

Destination address
Source address
Service port

1. host address (/32) - host address (/32) -port
2. host address (/32) - host address (/32) - *
3. host address (/32) - NETWORK address (/24 /25...) -port
4. host address (/32) - NETWORK address (/24 /25...) -*
5. host addres (/32) - * - port

So correct is VS2
