Dear Parliamentary Information Service,
I would appreciate a response to my information request.
During the period leading up to the coming election, it is important to have transparency on what edits are being made to public internet resources from the government's IT infrastructure.
Yours sincerely,
J. P. W. Pitt

Thanks Alex - I'll make any followup more specific. Currently my main interest is to allow traceability of wikipedia edits.

May pay to clarify some of the IP ranges (ask for the appropriate CIDR) as they aren't owned by Parliamentary Service, and in some cases I suspect if used for certain purposes include non-Parliamentary Service computers (particularly those in the 'Cable Customers' allocation).
> 202.22.16.0
> 202.22.18.0
> 202.22.30.0
All come from "inetnum: 202.22.16.0 - 202.22.30.255" owned by Vodafone NZ, so it's possible that they have been assigned /24's from those ranges, but it's possible that they are only assigned certain IPs.
> 202.49.210.0
> 202.49.211.0
> 202.49.212.0
> 202.49.213.0
> 202.49.214.0
> 202.49.215.0
From allocation to Parliamentary Services:
inetnum: 202.49.208.0 - 202.49.215.255
netname: PS-NZ
descr: Parliamentary Service NZ (PS)
(CIDR = 202.49.208.0/21) But their response implies they don't use 202.49.208.0/24 or 202.49.209.0/24 (sub-assigned to another purpose that Parliamentary Services admin?)
> 202.68.89.0
Part of allocation matching "inetnum: 202.68.80.0 - 202.68.95.255" (Netname: DTS - a Business ISP, so similar concerns to below if they are only using a couple of IPs from that particular /24).
> 203.97.232.0
Part of allocation matching "inetnum: 203.97.220.0 - 203.97.236.255" (Description per WHOIS: "TelstraClear Cable Customers") concern here is if used to identify traffic from P.S. it could include false positives from other TelstraClear customers.
From: J. P. W. Pitt
Dear Parliamentary Information Service,
Thank you very much for your reply!
The previous reply indicates /24 netmask for all networks but on investigation this seems is unlikely (see below). Could you please clarify some of these, preferably using a more specific CIDR?
Some of the ranges in your response are not owned by Parliamentary Services, e.g. some are indicated as in use for 'Cable Customers'. but for accountability it is necessary to have more specific ranges to avoid conflating traffic from individual/business internet users from that of parliament.
> 202.49.210.0
> 202.49.211.0
> 202.49.212.0
> 202.49.213.0
> 202.49.214.0
> 202.49.215.0
From allocation to Parliamentary Services:
inetnum: 202.49.208.0 - 202.49.215.255
netname: PS-NZ
descr: Parliamentary Service NZ (PS)
(CIDR = 202.49.208.0/21) Your response implies parliamentary services does not use 202.49.208.0/24 or 202.49.209.0/24. Is this correct?
> 202.22.16.0
> 202.22.18.0
> 202.22.30.0
All come from "inetnum: 202.22.16.0 - 202.22.30.255" owned by Vodafone NZ.
> 202.68.89.0
Part of allocation matching "inetnum: 202.68.80.0 - 202.68.95.255" (Netname: DTS - a Business ISP).
> 203.97.232.0
Part of allocation matching "inetnum: 203.97.220.0 - 203.97.236.255" (Description per WHOIS: "TelstraClear Cable Customers").
For the above three network owners, has Parliamentary Services been allocated /24's from the ranges? Or only certain IPs?
Also, your response suggests that Parliamentary Services does not use any external IPv6 addresses. Can you confirm that all outbound Parliamentary Services traffic is limited IPv4 only?
Yours sincerely,
J. P. W. Pitt

As you acknowledge in your request, the Parliamentary Service is not subject to the OIA. They sometimes respond out of courtesy, but they're under no obligation to, and they are not bound by any statutory timeframe.
Being more specific in why you're asking - e.g. so we can monitor Wikipedia for edits made by parliamentary staffers - might help.
