I was a little disconcerted when I accessed my abooks.com web page last
night and it welcomed me as coming from "none."<g> Obviously, some IP
numbers do not have names associated with them. So I modified my
modification of wherefrom.r to make more sense, to wit:
#!/rebol/rebol --cgi
REBOL
]
ip: system/options/cgi/remote-addr
print "Content-Type: text/plain^/"
print "<font face='ARIAL' size='-2'>"
print ["Thank you for visiting this page from<br>IP: "
ip "- - - Name: " read join dns:// ip]
print [<br>" on"
now/date "at" now/time "our time (U.S. Eastern)."
]
print "<BR><BR></font>"
which gives the result:
Thank you for visiting this page from
IP: 207.205.134.55 - - - Name: pool-207-205-134-55.atln.grid.net
on 6-Oct-1999 at 11:31:41 our time (U.S. Eastern).
