/**
* \ingroup address
*
* \brief a class to store IPv4 address information on an interface
*
* Corresponds to Linux struct in_ifaddr. A list of these addresses
* is stored in Ipv4Interface. This class is modelled after how current
* Linux handles IP aliasing for IPv4. Notably, aliasing of IPv4
* interfaces (e.g., "eth0:1") is not used, and instead an interface
* is assigned possibly multiple addresses, with each address being
* classified as being primary and secondary. See the iproute2
* documentation for this distinction.
