This packet allegedly came from www.anonymizer.com (168.143.113.10). It apparently has undergone NAT, so its contents might have been garbled, but: In contrast to Piotr's packets, this one does contain an OPT RR (type 0x29). The sender buffer length (encoded in the class field of the RR) is set to 10000.
