Additionally, the below displayed page offers ten
Uniform Resource Locators URLs selections to be
verified over several possible time allocations as well as
choosing the amount of desired tests. These different
URLs options allow testing of either an Internet Protocol
(IP) number or a Domain Name System (DNS) address
and in computer networks, both IP and DNS respond for
the location of a sought resource, that is, data
(Tanenbaum and Wetherall, 2010) and noted that, on
the World Wide Web, data is typically held at a
website, consistently and continuously testing if a
URL is available acquires an enhanced implication.
Especially when that most accessed websites in the
Internet offer media content, i.e., images, music
and/or video (Technavio, 2014).
