Internet protocol (IP) version 4 addressing policy

Policy

Final | February 2017 | v3.0.0 | PUBLIC | QGCIO

Purpose

This Queensland Government Enterprise Architecture (QGEA) policy states the Queensland Government’s direction with respect to the use of Government owned public version 4 IP address ranges. Public addresses are addresses that are able to be accessed via the internet. Version 4 is the current address format, and the address space is predicted to be exhausted in approximately three to four years based on current usage patterns.

Policy statement

Queensland Government Chief Information Office will centrally govern IPv4 IP address ranges according to an approved governance framework.

Policy benefits

This policy will help to ensure that, as IPv4 addresses become scarce, the Queensland Government has continued access to sufficient publicly accessible IPv4 addresses for future service provisioning requirements. The policy will also ensure more efficient accessibility to government electronic services by simplifying network services between agencies.

The implementation of the policy will also provide a clearer view of the current state of Queensland Government IP addressing requirements. These requirements will form the basis of a future IP version 6 policy for the Queensland Government.

Scope

IP version 6 Address ranges are outside the scope of this policy.

Applicability

This policy applies to all Queensland Government departments and any Government-owned corporations or Statutory Authority connected to the whole-of-government network.

Policy requirements

Policy requirement 1 : All agencies to adhere to the IPv4 interconnection standard

Network connections between Queensland Government bodies and with the whole-of-government network will be in accordance with the IPv4 interconnection standard.
