addresses in their Web browsers.
Analysis

name and tries to resolve the string. If the resolution fails, the operating system sends an ARP request,
but the target address is not in the dotted decimal notation. The redirection feature does redirect this
kind of ARP request.
• The address is within a free IP segment. No redirection will take place, even if no host is present with
the address.
The redirect URL is not in a free IP segment.

No server is using the redirect URL, or the server with the URL does not provide Web services.

3. If the problem persists, contact HP Support.
