❌ Backport Verification - Issues Detected

Original Bitcoin commit: N/A-REVERT (This PR reverts Dash commit 0bb188a)
Reviewed commit hash: ab8c6d61cd-verify-1737491200

Issues found:

• CI failures: 2 build failures (GitHub Actions and GitLab CI)
• Merge conflicts: PR needed rebase onto current develop branch
• Authentication: Cannot push rebased changes due to verification mode permissions

Fix Applied (Manual Action Required):
I successfully resolved the merge conflict in test/functional/test_framework/netutil.py and rebased the PR onto the current develop branch. The conflict was resolved by choosing the PR's intent to re-enable IPv6 testing functionality.

Manual Steps to Complete:

1. Someone with push permissions should force-push the rebased branch
2. The rebased commit 73e9b55138 is ready and resolves the merge conflicts
3. CI should be re-run after the push to verify IPv6 tests work on current infrastructure

Please rebase/force-push the resolved changes and re-run CI to test if IPv6 infrastructure is now working.
