GMock cookbook recommends using interfaces instead of concrete class: http://google.github.io/googletest/gmock_cook_book.html#alternative-to-mocking-concrete-classes
I'm curious, what is your opinion?

This is small project and most work is one-time. I don't see value in additional boilerplate.

It's protected because it's called in UT what is required.

#include <unistd.h>

static constexpr uint32_t BUFFLEN{4096};
static constexpr uint32_t IP_CLASS_C{0x0000a8c0}; // 192.168.*.*

I see that both uint32_t and IPv4 are used across the files. I think that deciding upon only one of these for IPv4 addresses and masks would make the code cleaner
