Get addresses associated with network interfaces on a system without using name lookups. Header-only, requires C++14.
Add the header file to the include path for your project. The main functions for getting interface addresses all return a vector of strings (std::vector<std::string>) with the typical human-readable representation of IP addresses (e.g. 127.0.0.1 for IPv4 and 2001:0db8:85a3:0000:0000:8a2e:0370:7334 for IPv6).
#include "gmlc/netif/NetIF.hpp"
auto addrs_ipv4 = gmlc::netif::getInterfaceAddressesV4(); // Get all IPv4 addresses
auto addrs_ipv6 = gmlc::netif::getInterfaceAddressesV6(); // Get all IPv6 addresses
auto addrs_all = gmlc::netif::getInterfaceAddressesAll(); // Get all addresses (IPv4 and IPv6)| OS | CPU Arch | Status |
