11. **Protocol Enumeration:** Ensure the `Protocol` enum includes the `ARP` variant and is integrated in `Protocol::ALL`.
 22. **Packet Analysis Logic:**
 3   - Properly detect ARP packets within `analyze_headers` and `analyze_network_header`.
 4   - Appropriately extract ARP sender/target IPs based on the protocol (IPv4 or IPv6).
 5   - Track and store ARP operations (Request, Reply) using the `ArpType` enum.
 63. **Display & User Interface:**
 7   - Accurately represent ARP packet types in the UI (`connection_details_page.rs`) alongside ICMP types.
 8   - Skip displaying service information for ARP packets in line with ICMP behavior.
 94. **Data Struct Enhancements:**
10   - Update `InfoAddressPortPair` to store and count ARP operation types.
11   - Ensure filtering and presentation logic uses ARP data correctly.
125. **Default Behaviors:**
13   - Set default `protocol` in `PacketFiltersFields` to `ARP` for consistency.
146. **Testing:**
15   - Update unit tests for `Protocol::ALL` and `get_service` to account for ARP behavior.
16   - Confirm that ARP protocol toggling works properly in the GUI protocol filter handling.
