Not sure at exactly what level you're looking to improve it!
Could you improve the query so you didn't have to search through all the
records? i. e. add in '..where IPAddress = $getaddr" That way you could do
away with the while loop altogether.
If you can't then why not break out of the while as soon as you've found the
IPaddress you're looking for - i.e.
if ( $found = $getaddr == $mydata->IPAddress ) break;
And finally, if you were really having a downer on if statements you could use
the ternary operator form as in:
document.write( ( $found ) ? "...already vistied" : "insert..." );
Whatever you use, I think Robert's layout not only shows elegance and panache
but also makes it much easier to read.

visited your site.
