Set or return the Internet address for the remote host.
A string value which specifies the Internet address in dot notation.
Setting the HostAddress property causes the control to submit a reverse query to the nameservers that you have specified. If a reverse entry is found for the IP address, the HostName property is changed to that host name.
Note that reverse domain name records (PTR records) may not be defined for a system and the application must not depend on this information being available.
