Stop making all the things strings or abstract base classes. Easy example I've worked on recently. An IPv4 address is an IPv4address in code. I don't care if it is just represented as an uint32 or string in Memory, in your code it should be an IPv4 address and if a function expects an IPv4 address and you pass it a string that is a compilation error.
