Happy New Year to you too! (Or "have a Happy New Year", as it's now still 2023-12-30 23:04 local time here. :-))

Because either
1) you don't have network-layer host name resolution enabled
or
2) it's enabled, but Wireshark couldn't translate the IP address to a host name.

To make sure network host name resolution is enabled:
select "Preferences" from the "Edit" menu (Windows, Linux, everything else other than macOS) or the "Wireshark" menu (macOS);
select "Name Resolution" from the Preferences dialog;
make sure that "Resolve network (IP) addresses" is checked;
make sure that "Use your system's DNS settings for name resolution" is checked;
click the "OK" button.
If that doesn't cause it to resolve IP addresses, it's probably because whatever DNS server your system's DNS settings use can't resolve the addresses.

I don't think there's a "whois" menu item in Wireshark.

There are, but "whois" isn't one of them. There may have, in the past, been a "resolve IP address(es)" option, but it doesn't appear to be there now.
