No, they don't ping your machine to get your address. If you are
connecting to a server (whether whitehouse.gov or any other) they will
have your IP automatically (unless you are using a proxy service or
anonymizer of sorts). It's how TCP/IP works. When you initiate a
connection your computer sends a SYN packet from your public IP to the
server. The server acknowledges the packet by sending a SYN ACK
packet back to your IP. Your computer then sends an ACK packet back
and the three way handshake is then done. So already by this time
before any content is transferred to your computer the server knows
your IP. It has to know your IP in order to send packets of data to
it with the content of the site. It does not need to ping your
machine. And if it were to send a ping, it would have to know your IP
in order to ping it so again no need to ping you as they would already
having it.

You are probably confusing this with some suggesting you turn ping
reply off on your router so it does not reply to ping packets. The
purpose of that is so malware that is pinging a range of IPs looking
for machines online will not get a response back from your IP thus
leaving the malware with one of two possibilities, no host is
currently live at that IP (so no point attacking it), or the host at
that IP is ignoring pings.
