What DNS server does the client MOEDW1CKH5 think is it's DNS? If it's a
linux client then check /etc/resolv.conf to see or sniff the wire for

You've told dnsmasq to send a lease with option 6 (DNS) set to
10.88.13.3. Where dnsmasq forwards the queries to is not relevant to
your issue, you only have one upstream server configured.
