Create a new host address for a specific internet host. 

The internet host can be specified in a null terminated ASCII string and include either the physical host address or the DNS name of a host machine. Hence, an {\bf IPV4Host}{\rm (p.\,\pageref{classost_1_1_i_p_v4_host})} (\char`\"{}www.voxilla.org\char`\"{}) can be directly declaired in this manner.

Defaults to the IP address that represents the interface matching \char`\"{}gethostname()\char`\"{}.

\begin{Desc}
\item[Parameters:]
\begin{description}
\item[{\em host}]dns or physical address of an Internet host. \end{description}

Convert a system socket binary address such as may be returned through the accept() call or getsockpeer() into an internet host address object. 

\begin{Desc}
\item[Parameters:]
\begin{description}
\item[{\em addr}]binary address of internet host. \end{description}
