Within the browser, the sitename ABC.com is resolved to an IP address(es) via DNS lookups and then connection attempts will be made to the resolved IP.

In the capture, if the connection is using TCP, you should see TCP packets with the SYN flag being set to the resolved IP addresses, usually on port 80 (HTTP) or port 443 (HTTPS). Some browsers now use QUIC which are UDP packets, usually to port 443.
