Focus on Canada (929 images)
The 929 images hosted on unique IP addresses in Canada can be broken down as
follows:
A 47.1% (438) were hosted by a website designed specifically to allow public
hosting of images. Almost all of the images on this website were unique based
on the SHA-1 value; only three of the images were observed twice, on different
IP addresses.
B 24.8% (230) were hosted on a website that changes content on a regular basis.
It is most often in the form of a portal page that sells memberships or provides
links to websites hosting child abuse images. An additional 1.6% (15) of images
are hosted on a different service but, based on published information about the
owners of the sites, appear to be owned by the same provider.
C 8.2% (76) of the images appear to be made available in Canada on a website that
allows users to create personalized social networking websites. The images and
videos on these personalized pages were made available through a content
delivery network.
d 4.6% (43) of the images were hosted by a webhost and colocation provider. They
appear on a wide variety of websites, without a typical layout or content.
E The remaining 13.7% (127) of images were hosted in Canada on at least 13
different services.

Reports pertaining to Canadian-hosted images may be over-represented due to the
fact that the majority of the tipline’s INHOPE partner hotlines, who are trained to
assess illegal content in their respective jurisdictions, submit reports to Cybertip.ca
if the content they receive appears to be hosted in Canada. This increases the overall
proportion of Canadian-hosted content that is reported to Cybertip.ca. Of the 515
confirmed child pornography websites submitted to Cybertip.ca by the Internet Watch
Foundation in the United Kingdom, 95.3% (491) were hosted in Canada at the time of
analysis.
86.3% of unique images hosted in Canada were found on only one of five
Internet services.
Some webpages are hosted on multiple IP addresses. These can be hosted in the
same country (as is most often the case) or in any different number of countries.
Since Cybertip.ca began tracking and recording multiple IP addresses, 17 3,109
webpages hosting child sexual abuse images have been analyzed, 2,809 (90.3%) of
which have only been hosted on a single IP address. Of the remaining (300), the
number of hosts ranges from 2 to 19.
