Code Review

This pull request adds test coverage for the anonymizer property on IP address responses. The changes are straightforward and correct, including updates to test fixtures and new assertions. I've provided one suggestion to improve the readability of the new tests by grouping related assertions.

[gemini-code-assist]

For improved readability and conciseness, you can group these related expectations for the anonymizer object using RSpec's have_attributes matcher. This makes the test easier to read and maintain.

      expect(m.ip_address.anonymizer).to have_attributes(
        confidence: 99,
        anonymous?: true,
        anonymous_vpn?: true,
        hosting_provider?: true,
        public_proxy?: true,
        tor_exit_node?: true,
        network_last_seen: Date.new(2025, 1, 15),
        provider_name: 'TestVPN'
      )
