What is an IP address and does Vodafone offer IPv6?
Every device that wants to connect to the internet – whether it’s a computer, gaming console, smart TV, or something else – must have its own unique address to be recognizable to other devices. For this purpose, we use two versions of IP addresses:
- IP Version 4 (IPv4): Consists of four numbers separated by dots, for example, 154.211.133.201. The total number of these IP addresses is no longer sufficient for all devices connecting to the internet today.
- IP Version 6 (IPv6): Consists of eight groups of letters and numbers separated by colons, for example, 2001:0db8:0000:0000:0000:8a2e:0370:7334. There are many more of these addresses, allowing more new devices to connect to the internet.
You don’t need to remember the IP addresses of individual devices because machines do this work for you. For example, try entering the address 217.77.163.138 into your browser. Vodafone internet customers have access to a connection that works seamlessly with both generations of IP addresses, IPv4 and IPv6.
You can find out your current IP address and the IP protocol being used by visiting www.mojeip.cz. If you have a dynamic IP address, your IP address will change over time. In the case of a static IP address, it remains the same.
In what case will I be assigned an IPv6 address?
- We support the IPv6 protocol across our entire mobile network and almost the entire fixed network. If possible, your device will be assigned an IPv6 address.
- In our network, we use a dual-stack mode, which allows the simultaneous use of both versions of the IP protocol – IPv4 and IPv6. This means that your device can receive both addresses at the same time. This mode ensures compatibility and smooth operation of the connection, even if some devices or networks only support one of the IP protocol versions.
The authentication web page says I don't have IPv6, how can I change it?
You can easily test if you have an IPv6 connection by opening this web page. If you don't have an IPv6 address, the reasons may be:
- Your device (modem, phone, tablet, etc.) only supports IPv4 - in this case, you will automatically use the IPv4 protocol to ensure your connection works correctly.
- IPv6 is not enabled on your device - in some modems, phones, and other devices, IPv6 support needs to be turned on. You can find information in your device’s manual. On Android phones, you can adjust this in the Settings - Mobile Networks - Access Point Names section, where you select ‘IPv4/IPv6’ in the APN protocol if available.
- Your phone or tablet downloads network settings automatically, and IPv6 settings are not yet available for it - in this case, you need to wait, as carrier settings updates occur several times a year. Once you receive the new settings, IPv6 will be available.
- You are using a Vodafone connection for which we do not yet offer IPv6 - currently, we do not support IPv6 on some fiber connections, but we plan to in the future.
