IPv6 at PROLVL
The modern internet protocol is already on the PROLVL network. IPv6 works alongside IPv4, keeping your familiar websites and devices connected.
What is IPv6?
An IP address identifies a device on a network. IPv4 uses 32-bit addresses, such as 192.0.2.1. IPv6 uses 128-bit addresses, such as 2001:db8::1. These examples are for explanation, not router configuration.
IPv6 offers far more addresses. Devices can receive their own global IPv6 addresses without sharing an IPv4 address through NAT. This does not automatically open access: a firewall controls it.
What you get
A /64 subnet for your home network: an address space for your devices, rather than just one address. A single /64 is normally used for one local network.
IPv4 and IPv6 operate together (dual-stack). Devices and services choose an available protocol; older devices continue to use IPv4.
Remote access to your own services is possible over IPv6 if both ends support it, the service is configured and the firewall permits the connection. Ask support about prefix stability and availability for your connection.
How to connect
Check that your router supports IPv6 and DHCPv6-PD (Prefix Delegation), which obtains a subnet from the provider for your local network. Update firmware following the manufacturer’s instructions.
Enable IPv6 and DHCPv6-PD prefix requests. Set DNS to automatic and enable automatic LAN prefix advertisements (RA/SLAAC), where available.
Keep your working IPv4 settings. Do not choose tunnel modes such as 6to4, 6rd or Teredo at random. Menu names and WAN mode depend on your router and connection; support can help choose the right settings.
Save your settings and reconnect to the internet. Check the delegated prefix on the router and the IPv6 address on your phone or computer.
How to test
Open test-ipv6.com on a device connected to your PROLVL network. Turn off mobile data when testing your home connection; a VPN or proxy can affect the result.
10/10 means the IPv6 checks passed, not a speed rating. 0/10 means the test did not confirm a working IPv6 connection on this device; IPv4 may still work.
For a partial score, open the test details: router, device, VPN or network settings may be responsible. Save the result for support; do not publish your IP address publicly.
Test IPv6 ↗If it does not work
After reconnecting, check that the router has obtained its IPv6 prefix again and advertises it on the LAN. Reconnect the device’s Wi-Fi or Ethernet cable, then retest.
An address starting with fe80: is link-local and does not prove internet connectivity over IPv6. A WAN IPv6 address alone is also insufficient: you need a delegated prefix and a configured LAN.
Tell support your contract number, router model and firmware version, connection type, problem time and test-ipv6.com result. Include screenshots of IPv6 settings without passwords. Do not disable the firewall for testing.
Security and remote access
Keep the IPv6 firewall enabled on your router and devices. Allow incoming connections only to the services you need and, where possible, from trusted addresses only.
Do not expose the router’s administration panel to the internet. Prefer a properly configured VPN for home-network access and protect services with passwords and updates.
Do not block all ICMPv6: IPv6 needs it to work correctly. Use the manufacturer’s standard firewall rules. Addresses and prefixes may change; do not assume they are permanent without confirmation from support.
Frequently asked questions
Will my connection get faster?
IPv6 does not change your plan’s speed. Routes to some services may differ, but we do not promise automatic speed improvements.
Do I need a public IPv4 address?
Not to access IPv6 services. IPv6 alone cannot provide direct access from IPv4-only networks; a public IPv4 address or another solution may be needed.
Will older devices still work?
Yes, if they worked over IPv4: IPv4 remains available alongside IPv6.
Do I need to enter DNS manually?
Usually not: select automatic DNS on your router and devices. A DNS server does not need an IPv6 address to resolve IPv6 services.
Do I need a new router?
Only if yours lacks the required IPv6 features, including DHCPv6-PD. Ask support about your model before buying.
We can help check your router and configure IPv6.
