Official Information Act 1982 (OIA) request dated 29 July 2022 (ref OIA2223-0083)
Thank you for your OIA request dated 29 July 2022 to the Department of Internal Affairs
(Department). You asked for the fol owing information:
1) The number of IP addresses (or prefixes) currently present in the "routing
information" advertised to an Internet Service provider (as described at
https://www.dia.govt.nz/Digital-Child-Exploitation-DCEFS-Public-Information-Pack).
2) The number of URLs currently listed as blocked.
3) A [breakdown] of how many incoming requests handled by the DCEFS are HTTP (TCP
port 80) vs HTTPS (TCP port 443) over your most recently available reporting period.
4) Details of how the DCEFS system "examines" incoming requests that are secured
using the HTTPS protocol.
5) The number of view or "hits" on the landing page displayed when a site is blocked for
your most recent available reporting period.
Response to your request
Our response to each part of your request is outlined below.
Part one: The number of IP addresses (or prefixes) currently present in the "routing
information" advertised to an Internet Service provider (as described at
https://www.dia.govt.nz/Digital-Child-Exploitation-DCEFS-Public-Information-Pack).
As at 4 August 2022 there are 205 IP addresses (or prefixes) present in the “routing
information” advertised to an Internet Service Provider.
Part two: The number of URLs currently listed as blocked.
As at 4 August 2022 there were 425 URLs listed as blocked.
Part three: A breakdown of how many incoming requests handled by the DCEFS are HTTP
(TCP port 80) vs HTTPS (TCP port 443) over your most recently available reporting period.

Part four: Details of how the DCEFS system "examines" incoming requests that are secured
using the HTTPS protocol.
The DCEFS does not filter requests that are secured using the HTTPS protocol. Therefore, al
of the requests handled by the filter are HTTP. We do not hold the information you
requested, and we cannot think of any other agency that would hold it, or whose functions
would be more closely connected to it. Therefore, parts three and four of your request are
refused under section 18(g) of the OIA.
Part five: The number of view or "hits" on the landing page displayed when a site is blocked
for your most recent available reporting period.
There were 277,346 pageviews in the most recent reporting period, which was from 1 March
to 31 May 2022. Please note that during a portion of this period, from 17 to 29 May 2022,
the reporting function in Google Analytics was accidental y turned off. This is unrelated to
the filter which was operational and performing as expected.
Access to the Ombudsman
If you are dissatisfied with our decision on your request for information, you have the right,
under section 28 of the OIA, to make a complaint to the Office of the Ombudsman. The
Office of the Ombudsman can be contacted by phone on 0800 802 602, via post at PO Box
10152 Wel ington, or via email t
o [email address].
