+<p>Compared to the <span>net.IP</span> type, <a href="#Addr">Addr</a> type takes less memory, is immutable, and is comparable (supports == and being a map key). </p>     <h2 id="pkg-index">Index </h2>  <ul id="manual-nav">

That is, it reports whether ip is in 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16, or fc00::/7. This is the same as <span>net.IP.IsPrivate</span>. </p>
