<h2>Description</h2>
<div class="description">
<p>This class represents an internet (IP) host address. The address can belong either to the <a href="Poco.Net.IPAddress.html#13595" title="Poco::Net::IPAddress::IPv4">IPv4</a> or the <a href="Poco.Net.IPAddress.html#13596" title="Poco::Net::IPAddress::IPv6">IPv6</a> address family. </p>
<p>Relational operators (==, !=, <, <=, >, >=) are supported. However, you must not interpret any special meaning into the result of these operations, other than that the results are consistent. </p>
<p>Especially, an <a href="Poco.Net.IPAddress.html#13595" title="Poco::Net::IPAddress::IPv4">IPv4</a> address is never equal to an <a href="Poco.Net.IPAddress.html#13596" title="Poco::Net::IPAddress::IPv6">IPv6</a> address, even if the <a href="Poco.Net.IPAddress.html#13596" title="Poco::Net::IPAddress::IPv6">IPv6</a> address is <a href="Poco.Net.IPAddress.html#13595" title="Poco::Net::IPAddress::IPv4">IPv4</a> compatible and the addresses are the same. </p>
<p><a href="Poco.Net.IPAddress.html#13596" title="Poco::Net::IPAddress::IPv6">IPv6</a> addresses are supported only if the target platform supports <a href="Poco.Net.IPAddress.html#13596" title="Poco::Net::IPAddress::IPv6">IPv6</a>. </p>

<h3><a name="13616">toString</a></h3>
<p class="decl">std::string toString() const;</p>
<div class="description">
<p>Returns a string containing a representation of the address in presentation format. </p>
<p>For <a href="Poco.Net.IPAddress.html#13595" title="Poco::Net::IPAddress::IPv4">IPv4</a> addresses the result will be in dotted-decimal (d.d.d.d) notation. </p>
<p>Textual representation of <a href="Poco.Net.IPAddress.html#13596" title="Poco::Net::IPAddress::IPv6">IPv6</a> address is one of the following forms: </p>
<p>The preferred form is x:x:x:x:x:x:x:x, where the 'x's are the hexadecimal values of the eight 16-bit pieces of the address. This is the full form. Example: 1080:0:0:0:8:600:200A:425C </p>
<p>It is not necessary to write the leading zeros in an individual field. However, there must be at least one numeral in every field, except as described below. </p>
<p>It is common for <a href="Poco.Net.IPAddress.html#13596" title="Poco::Net::IPAddress::IPv6">IPv6</a> addresses to contain long strings of zero bits. In order to make writing addresses containing zero bits easier, a special syntax is available to compress the zeros. The use of "::" indicates multiple groups of 16-bits of zeros. The "::" can only appear once in an address. The "::" can also be used to compress the leading and/or trailing zeros in an address. Example: 1080::8:600:200A:425C </p>
<p>For dealing with <a href="Poco.Net.IPAddress.html#13595" title="Poco::Net::IPAddress::IPv4">IPv4</a> compatible addresses in a mixed environment, a special syntax is available: x:x:x:x:x:x:d.d.d.d, where the 'x's are the hexadecimal values of the six high-order 16-bit pieces of the address, and the 'd's are the decimal values of the four low-order 8-bit pieces of the standard <a href="Poco.Net.IPAddress.html#13595" title="Poco::Net::IPAddress::IPv4">IPv4</a> representation address. Example: ::FFFF:192.168.1.120 </p>
