Bug report: ExtractIPAddresses function IPv6 matches incorrectly when multiple IPs in one-line

[BlacAmDK]

Describe the bug
The original IPv6 regex code in ExtractIPAddresses only worked fine when it matched the whole one-line text, if it has multiple IPs in one line, it will break sometimes.

Expected behaviour
When multiple IP in one-line, it can be matched correctly.
