- Avoid referencing conditions we know are false/true
- Avoid using name of imported package as variable
- Avoid broken (see list item 1) if else statement in `ipservice.go` by refactoring to switch statement
- When assigning a pointer value to a variable along with an error, check that error before referencing that pointer. Thus avoiding de-referencing a nil and causing a panic.
*** This item is the most important ***
- Standard gofmt package sorting + linting; This includes fixing comment starts for go doc
- Explicit non-handling of unhandled errors where appropriate (assigning errs to _ to reduce linter screaming)
- Export ErrExpired in `netcache` package so that we can properly reference it using `errors.Is` instead of using `strings.Contains` against an `error.Error()` value
