網際網路已成為生活上不可或缺的一環，從早期的電腦使用，已演變到無所不在，物物連網都需要有 IP 的重要基礎設施。台灣 IP 位址核發數量，在 IPv4 位址發放數量統計上，台灣至2018年底共取得 3,565 萬個 IPv4 位址，數量居全球第 15 名；取得的 IPv6 數量為 2,476 個 /32 IPv6 位址；核發的自治系統號碼（ASN）為 354 個。

IP（Internet Protocol）位址即網際網路協定位址，如同門牌地址，主要提供用戶於網際網路上接收與傳送資訊。因應全球IPv4位址用罄，啟用IPv6更符合未來多元行動終端及萬物聯網發展需求，尤其是物聯網、智慧家庭、車聯網/自駕車、智慧城市及醫療健康照護等應用。網際網路版本6（IPv6, Internet Protocol version 6）是下一代網際網路協定，它被設計用來替代當前網際網路通訊協定IPv4，位址長度由32位元提升至128位元，IPv6位址空間多達2的128次方個位址。因此，IPv6可以直接解決物聯網面臨之位址不足問題，並且保持網路互連透通性，物體裝置可以進行任何形式之雙向連線。

台灣IPv6 使用比例於2018年底為29.63%，全球排名第6名。

依據APNIC IPv6量測網站資料指出，2017年12月台灣IPv6比例僅0.38％，排名全球第67。但國內中華電信2018年年初4G行動上網開始提供IPv6商用服務，5月HiNet光世代及公眾Wi-Fi逐步啟用IPv6，使台灣IPv6使用比例快速竄升，至9月達到17.05％，增加了約45倍，全球排名近期躍升至25名，成長速度今年創世界第一，台灣 IPv6 使用比例於2018年底為 29.63%，全球排名第 6 名。

The Internet has become an indispensable part of modern life. From an era when the Internet was only available on computers, it has evolved to become omnipresent. Currently, almost all modern devices require an IP address to be connected to the Internet. At the end of 2018, Taiwan was ranked 15th globally in terms of the number of IPv4 addresses possessed (i.e., 35.65 million addresses). The number of IPv6 addresses obtained by Taiwan by the end of 2018 was approximately 2,476 /32 IPv6 address blocks, whereas the number of autonomous system numbers issued was approximately 354.

An IP address is similar to a property address in real life. Its purpose is to enable users to receive or transmit information on the Internet. In response to the global exhaustion of IPv4 addresses, IPv6 was introduced to replace IPv4. IPv6 is regarded as being able to better fulfill the developmental needs of future diversified mobile terminals and Internet of Things (IoT) technology, particularly for IoT applications, such as smart homes, Internet-connected vehicles/self-driving cars, smart cities, and medical healthcare applications. The length of IPv6 addresses is 128 bits (as opposed to 32 bits in IPv4 addresses), which means that IPv6 address space allows for 2¹²⁸ unique IPv6 addresses. Therefore, IPv6 can resolve the problem of insufficient addresses faced by the IoT industry and can maintain the transparency of network interconnections; devices can carry out any form of bidirectional connection.

The usage rate of IPv6 in Taiwan by the end of 2018 was 29.63%, and Taiwan ranked as the sixth largest IPv6 user globally.

According to data from the APNIC's website for measuring IPv6, the adoption rate of IPv6 in Taiwan in December 2017 was only 0.38%, meaning Taiwan was ranked 67th globally in terms of IPv6 adoption. However, at the beginning of 2018, Chunghwa Telecom started providing commercial IPv6 services for 4G mobile Internet. On May 2018, HiNet also started providing IPv6 services for its FTTx network services. In addition, public WiFi has been gradually transitioning toward IPv6 adoption. These factors have caused the IPv6 adoption rate in Taiwan to surge, reaching 17.5% by September 2018, which is approximately a 45-fold increase from the initial rate of 0.38%. Recently, the global ranking of Taiwan in terms of IPv6 usage moved up to 25th, and Taiwan's growth rate in IPv6 usage was ranked first in the word. The adoption rate of IPv6 in Taiwan by the end of 2018 was 29.63%, meaning Taiwan was ranked sixth in iPv6 usage globally.
