Enabling IPv6 adds a dedicated IPv6 address to your server, in addition to its IPv4 address. You can then use this new address to make a website or another service accessible via IPv6.
Enabling the address does not modify [PERSON_NAME] DNS zone of your domains. This configuration remains optional and must be done separately.
Before enabling IPv6
Check the security rules applied to your server, especially if you have limited certain accesses to specific IPv4 addresses.
A firewall rule or restriction configured only for IPv4 does not necessarily block IPv6 connections. After activation, [PERSON_NAME] that they also protect the server's IPv6 address.
Enable IPv6 on the server
- Log in to your LWS customer area.
- Go to the management of your [PERSON_NAME]>
- In the server management, click IPv6 Option in the Advanced Configuration section.
- Select Enable, then Validate.
The dedicated IPv6 address is set up on your server within a few minutes.
Check that the IPv6 address is active
Go back to the IPv6 Option section of your server. The option should appear as active and the IPv6 address [PERSON_NAME] assigned to the VPS should be indicated.
Activating the address does not mean that all server services are immediately accessible via IPv6. The web server, firewall, and other applications used must also accept IPv6 connections.
To make a website accessible with this address, you must then add an IPv6 [ADDRESS] DNS zone of its domain name.
[PERSON_NAME] point a domain to the IPv6 address
A DNS record of type AAAA allows a domain or subdomain to be associated with an IPv6 address.
You can keep the existing A record. The domain will then be able to use IPv4 and IPv6 depending on the connection available to the visitor.
If the DNS zone is managed at LWS
- Go to its DNS zone.
- [PERSON_NAME] an AAAA record already exists for the domain or subdomain concerned:
- if it exists, modify its value;
- if it does not exist, add a new record.
- Select the AAAA type.
- Enter the main domain or subdomain to configure.
- In the record value, enter the IPv6 address assigned to your VPS.
- Save the change.
[PERSON_NAME] know how to modify the DNS Zone of your domain, consult this documentation
[PERSON_NAME] accessible the main domain and the address starting with www, check that each has an appropriate DNS configuration. An AAAA record may notably be necessary for www if it is not already linked to the main domain by a DNS alias.
If the DNS zone is managed by another provider
Log in to the interface of the provider that supplies the DNS servers used by your domain, then create the same AAAA record.
[PERSON_NAME] know how to modify [PERSON_NAME], [ADDRESS] communicating:
- the domain or subdomain to configure;
- the record type: AAAA;
- the IPv6 address assigned to your VPS.
This procedure concerns pointing a domain or subdomain to the server.
Configuring an email service in IPv6 requires additional settings. Do not directly replace an MX record with an IPv6 address.
A DNS change may take several hours before it is visible everywhere. [ADDRESS], some visitors may still use the old configuration.
Common issues
I do not see the IPv6 option
Make sure you are managing the correct server. [PERSON_NAME] may be available on some plans or configurations. In this case, contact LWS support and specify the server concerned.
The IPv6 address is active, but my site [PERSON_NAME]
Check the following points:
- an AAAA record correctly points the domain to the right address;
- the web server accepts IPv6 connections;
- the firewall allows the ports used, generally ports 80 and 443 for a website;
- no security rule blocks IPv6 traffic.
My domain directs visitors to another server
Look for the AAAA records already present in the DNS zone. An old record may still send IPv6 connections to another address.
Modify or delete only the record that is no longer needed. Do not delete the A record if you want to keep access to the site via IPv4.
The DNS change is not yet visible
Wait a few hours, [PERSON_NAME] DNS zone. Also check that you modified the zone with the provider whose DNS servers are actually used by the domain.
