25
* Corresponds to Linux struct in_ifaddr. A list of these addresses
26

27
* Linux handles IP aliasing for IPv4. Notably, aliasing of IPv4
28
* interfaces (e.g., "eth0:1") is not used, and instead an interface
29
* is assigned possibly multiple addresses, with each address being
30
* classified as being primary and secondary. See the iproute2
31
* documentation for this distinction.
