Hi

 

 

I am using a controller installed on Linux.


I have disabled ipv6.
But the client is getting ipv6.
I don't want to assign ipv6. What should I do?

 

I have many routers connected to my controller, some of them are different models.
They all have the same issue.

 

In other things

And recently, after the firmware update, there was a bug where wifi 5g 2g individual configuration settings were merged into 5g 2g integrated broadcast configuration

 

and there was also a bug where ER707-M2 LAN3 was not used.

Thank you.

Hi  @itkairos 

 

IPv6 addresses that begin with “fe80” are IPv6 link - local address.

1. **Explanation of Address Type** - IPv6 addresses are divided into various types, and the link - local address is one of them. This type of address is mainly used for communication on a single link, such as a local local - area - network (LAN) segment.  Its function is similar to the Automatic Private IP Addressing (APIPA) addresses (169.254.x.x) in IPv4, which is used to enable communication between devices within the local - link range when there is no other configuration.

2. **Application Scenarios** - In a local network, devices use link - local addresses to discover other devices or for some local network - service discovery. For example, when a global unicast IPv6 address is not configured or during the network - initialization stage, devices can use link - local addresses to perform operations of the Neighbor Discovery Protocol (NDP). Through NDP, devices can discover each other's link - layer addresses and check the reachability of addresses, which is very important for building local - network connections.

3. **Difference from Other Addresses** - Compared with global unicast IPv6 addresses, the scope of link - local addresses is limited to the local link. Global unicast addresses can be used for communication across the Internet, while link - local addresses are mainly used for communication within the local network and cannot be directly used to access the Internet. If a device wants to access an external network such as the Internet, it usually needs to obtain a global unicast IPv6 address or use some Network Address Translation (NAT - Pt and similar techniques) to achieve this.

As for the LAN3 feedback, we are aware of this now. 

The workaround is to change it as a WAN port first, then configure it as a LAN port again.

 

Thanks for the feedback, we will fix it soon.

  @Vincent-TP 

I want to disable IPv6 in my router settings so that clients don't use ipv6.

I'm currently disabling ipv6 as shown in the picture below. Is this the only way?

 

thank you

Yes, If you disable IPv6 on your computer, theoretically you will not see the IPv6 link-local address starting with "fe80::" (such as fe80::98f:d625:14f:8688) displayed for local network communication.
