Which option creates a display filter on Wireshark on a host IP address or name?

ip.address and ip.network are not valid Wireshark display filter field names; the correct field for address matching is ip.addr.

This syntax resembles tcpdump capture filter syntax focused on ports, not a Wireshark display filter for filtering by host address or name.

ip.name is not a valid Wireshark display filter field; the correct field for hostname-based filtering is ip.host.

Wireshark's display filter language supports ip.addr == <addr> to match any packet where the source or destination IP equals the specified address, and ip.host == <host> to match packets by resolved DNS hostname. These are the two valid built-in filter fields for identifying traffic by host identity. Using the 'or' operator between them allows either an address or a name match to return results.
