Vodafone Australia is a major telecommunications provider offering cellular data services via SIM-based mobile plans and fixed-wireless 4G/5G routers. Historically, Vodafone has positioned itself as a value-driven competitor to Telstra and Optus, often trading lower price points for a more condensed geographic coverage footprint.<ref>WhistleOut, "Who has the best mobile coverage?", https://www.whistleout.com.au/MobilePhones/Guides/who-has-the-best-mobile-coverage</ref> | Vodafone Australia is a major telecommunications provider offering cellular data services via SIM-based mobile plans and fixed-wireless 4G/5G routers.

As of June 2025, Vodafone has moved to deprecate native IPv4 addressing on its mobile broadband APNs. While modern smartphones and PC operating systems utilize dual-stack or transition mechanisms (like DNS64/NAT64) to maintain connectivity, many legacy devices lack the internal protocol stack to communicate over an IPv6-only network. | As of June 2025, Vodafone has moved to deprecate native IPv4 addressing on its mobile broadband APNs.

This follows a long-standing history of inconsistent IPv4/IPv6 implementation within Vodafone's infrastructure, which has previously caused routing issues for Australian consumers.<ref>Whirlpool Forums, "Vodafone IPv6," https://forums.whirlpool.net.au/archive/2770930</ref> | This follows a long-standing history of inconsistent IPv4/IPv6 implementation within Vodafone's infrastructure, which has previously caused routing issues for Australian consumers.<ref>Whirlpool Forums, "Vodafone IPv6," https://forums.whirlpool.net.au/archive/2770930</ref> | ||
==Vodafone's response== | |||
Vodafone technical support has stated that the removal of native IPv4 is a necessary step due to the global exhaustion of IPv4 addresses. Support representatives have indicated that IPv4 is considered a legacy protocol and suggested that competitors such as Telstra and Optus are moving toward similar IPv6-primary architectures.<ref>Direct correspondence with Vodafone Technical Support, June 2025</ref> | Vodafone technical support has stated that the removal of native IPv4 is a necessary step due to the global exhaustion of IPv4 addresses.
