Strange PTR queries

I'm seeing strange PTR-queries from my dhcp machine.
IP x.x.x.x.39782 > 184.108.40.206.53: 43960+ PTR? 220.127.116.11.in-addr.arpa.
IP 18.104.22.168.53 > x.x.x.x.39782: 43960 NXDomain 0/1/0 (117)
IP x.x.x.x.53299 > 22.214.171.124.53: 34386+ PTR? 126.96.36.199.in-addr.arpa.
IP 188.8.131.52.53 > x.x.x.x.53299: 34386 NXDomain 0/1/0 (118)
Has anyone seen something like that? I couldn't find any options in
dhcpd.conf or the manuals, related to this behavior (I have
"ddns-update-style none;" in the config, just in case you wonder if I'm
doing dynamic dns updates).
Thanks and best regards
