<p>Returns the broadcast address associated with the IPv4 address and netmask. It can usually be derived from those two by setting to 1 the bits of the IP address where the netmask contains a 0. (In other words, by bitwise-OR'ing the IP address with the inverse of the netmask)</p>
<p>This member is always empty for IPv6 addresses, since the concept of broadcast has been abandoned in that system in favor of multicast. In particular, the group of hosts corresponding to all the nodes in the local network can be reached by the "all-nodes" special multicast group (address FF02::1).</p>

<p>Returns the netmask associated with the IP address. The netmask is expressed in the form of an IP address, such as 255.255.0.0.</p>
<p>For IPv6 addresses, the prefix length is converted to an address where the number of bits set to 1 is equal to the prefix length.

<p>Returns the deadline when this address becomes deprecated (no longer preferred), if known.

<p>While an address is preferred, it may be used by the operating system as the source address for new, outgoing packets.

<h3 class="fn" id="prefixLength"><a name="prefixLength"></a><span class="type">int</span> QNetworkAddressEntry::<span class="name">prefixLength</span>() const</h3>
<p>Returns the prefix length of this IP address. The prefix length matches the number of bits set to 1 in the netmask (see <a href="qnetworkaddressentry.html#netmask">netmask</a>()). For IPv4 addresses, the value is between 0 and 32. For IPv6 addresses, it's contained between 0 and 128 and is the preferred form of representing addresses.</p>
<p>This function returns -1 if the prefix length could not be determined (i.e., <a href="qnetworkaddressentry.html#netmask">netmask</a>() returns a null QHostAddress()).</p>
