If you only want to capture UDP ports destined to a specific host on
port 53 here is an example (where host = 220.127.116.11):
(udp && dst host 18.104.22.168 && port 53)
So you could do this with Tcpdump:
/usr/sbin/tcpdump -vvvxXi <ethX> 'udp && dst host 22.214.171.124 && port 53'

I want to capture udp packets on port 53 to one host, including the
payload. I've figured out the hex address for the host, but the rest
