A DNS client wants to obtain the IP address of the computer www.uah.es (IPwww). It is known that the local DNS server only has the IP address of a root DNS server (IPr), that this root server only has the IP addresses of TLD servers (including the IP address of the DNS server with the .es domain), and that the Spanish DNS server has the IP address of the UAH's authoritative DNS server (the IPuah server named AuthUAH.es). Furthermore, only the local DNS server provides recursive access. Draw the DNS message exchange diagram.
