Obtains present ip-address for dynamically connected hosts.
Asp queries for the ip address of a host connected to Internet by using
the target host name and its probable ip-address range. Asp is usefull
when the nameserver of the queried host does not provide information
about its address ( common for hosts connected via ppp or slip
with dynamic ip allocation). Asp lets others find your host when it is
on-line, independently from your ISP; this is accomplished by running
a server (standalone or inetd version) on your host.
