This PR adds DNS options test coverage, but the domain assertion can pass even when the configured domain is wrong. Production behavior is unchanged, though the test should be tightened before merge.

One hundred fifty waits at the gate.

The options pass inspection best.
Ears twitch; the values are straight.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Assert the configured domain value.

len(opts.Domains) == 1 passes for any one-element slice. The test can pass when the configured domain is incorrect. Compare opts.Domains with []string{"rate.example.com"} or assert opts.Domains[0] directly.

Proposed assertion
-	assert.Equal(t, 1, len(opts.Domains))
+	assert.Equal(t, []string{"rate.example.com"}, opts.Domains)

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
