Overview
The Internet Protocol (IP) is the network layer which allows devices to talk to remote systems (eg a browser to a webserver) via a series of connections. An IP address is then the unique identifier which allows network devices to know where to route these packets and how the internet operates.
IPv6 is the next version of IP addressing, which works alongside the existing IPv4 addressing (as long as the devices are compatible). The reason for the new addressing is due to the fact that the total number of possible IPv4 addresses has reached a limit.
Conetix IPv6 Status
Currently Conetix is rolling out IPv6 across all services. Due to the size and complexity of our platform, this will take a considerable time to enable all servers and services. The rollout has already begun and we’re aiming to fully complete the rollout sometime in 2025.
This means if you use an external DNS service that provides IPv6 addresses or proxying via IPv6 (such as CloudFlare) your website will not resolve over the allocated IPv6 addresses for servers which haven’t been enabled yet.
This will cause Let’s Encrypt Certificates to fail issuing. A domain with an existing Let’s Encrypt certificate will fail to reissue if they were applied prior to the IPv6 records being implemented into your DNS zone.
To resolve we recommend removing “AAAA” records in your DNS zone for your domain.
Do I need to do anything to enable?
No. At this stage, we’re rolling the system out without requiring any manual intervention. If you have your DNS with Conetix, this will have the updated records added automatically.
You may require changes within your modem and/or Internet Service Provider to ensure you’re allocated an IPv6 address. Most ISP’s are providing both IPv4 and IPv6, however some are forcing the limit of IPv4 through the use of CGNAT and this may also cause issues.
How do I know if my service has been IPv6 enabled or not?
You and try and “ping” your service, or use a DNS tool such as DNS Checker to lookup the AAAA (IPv6) record. If the IP returned starts with 2403:6900, your service is working via IPv6.
