IPv6 entries: updating AAAA records

[DesertCookie]

Is there a way to update AAAA records using dnsupdater?

By default, dnsupdater tries to set my IPv4 address, failing at it, because in CloudFlare I have no A record. This is due to my ISP only providing IPv6 (common in Germany). More precisely, my IPv4 address is that of my ISP, shared with thousands of other people through DS-Lite.

INFO[0000] Loading configuration from C:\caddy\dnsupdater\config.yaml

Sorry, there's no IPv6 support for now.
I'll try to support IPv6, but my ISP only providing IPv4 addresses, which makes me hard to test. So I can't make a solid promise to you.

BTW, it seems you are trying to update a DNS record in Aliyun with errors? If you don't need to update any records in Aliyun DNS you can safely remove the whole AliDNSRecords part.

Feel free to contact me to test IPv6.

I already have removed the AliDNSRecords part. This is my reducted config file:

---
System:
  IPAddrAPI: "https://api.ipify.org/"
  CloudFlareAPIEndpoint: "https://api.cloudflare.com/client/v4"
CloudFlareRecords:
  - APIKey: "abcdefghijklmnop12345"
    ZoneID: "domain.ext"
    AuthEmail: "mail@provider.com"
    DomainName: "sub.domain.ext"

I've added support for updating IPv6 on the latest release, you can have a try.

And beware that there is a new property called DomainType in the config.yaml, so you need to update your config.yaml before trying this version.

Thank you for making an update this quickly! Here's what I found after testing:

1. Using your tool through PIA VPN returned an IPv4 address for the requested IPv6 address: msg="Current IPv6 address is: 186.221.71.136" (fair enough - exclude your tool from PIA).
2. The IPv6 address used by your tool is different from the one ipconfig returns me. Accessing my server via the IP directly like this [2001:16bb:576b:6512:1916:82df:6861:9900]:32400 works, but not via the domain.
3. While your tool successfully updates the IP, it disables proxying, exposing my host IP!

Points two and three should be easy enough fixes. In Java I got the IPv6 directly from the ethernet adapter, instead of a website - maybe you can do the same? Enabling proxying should be as easy as setting the corresponding flag in the HTTP request if I'm not mistaken...?

Sorry for the late response.

In short, I'm not going to do further developing on IPv6 support, instead, I'll remove it in the next version.

Here's the detailed explanation.

1. The reason why I decided to remove IPv6 support is that I have no public IPv6 address, which makes it hard to do any testing. Continue developing on this will cost too much effort to both you and me.

2. The only way for me to get my public IP address is to request it from an API, rather than from my ethernet card. So I'm not going to support fetching addresses from ethernet card.

My suggestion is, you can fork this repo and do your customization on top of it, or you can make your own application.

I'm going to close this issue. If you have any further questions, feel free to re-open it.

Also I think there is something I should let you know.

After I did some research, I found out that usually there are 3 IPv6 addresses on one computer: the link-local address, the temporary address, and the permanent address.

The link-local address is just like 127.0.0.1 in IPv4, nothing much to talk about.

The permanent address, which usually shown as IPv6 address in ipconfig, is the one you should never expose to anyone else. Because this address will not change, and others can trace to you with this address.

The temporary address is the one you can expose to others. It is generated with some sort of rules, and it will change after some time.
