> In the HDFS NameNode Web UI
> (http://nn-host:9870/dfshealth.html#tab-datanode), the "Http Address" column
> for DataNodes generates completely corrupt and invalid links when the
> DataNode's address is an IPv6 literal.
> 1. It fails to encapsulate the IPv6 address in square brackets `[]`, which is
> required by RFC 2732. 2. More critically, it appears to **parse the IPv6
> address incorrectly**, mistaking a part of the address (e.g., the `30` in
> `1172:30:...`) for the port number, which completely breaks the URL. This
> results in a malformed, unclickable link that does not point to the
> DataNode's web interface. **Current Behavior & Evidence:** The DataNode's
> actual address is: `[1172:30:0:0:0:0:8a34]:50010` However, the NameNode UI
> displays the link as: `https://datanodeHostname:30` This link is **invalid**
> and leads nowhere. The UI has: - Stripped the original port `50010`. -
> Incorrectly extracted `30` (which is part of the IPv6 address) and used it as
> the port. - Failed to wrap the IPv6 address, leading to incorrect parsing.
