57
LAN
Connection oriented and sends multiple packets
Transmission Control Protocol (TCP)
58
LAN
Connectionless and also sends multiple packets
User Datagram Protocol (UDP)
59

63
LAN
DNS uses hierarchical organization to resolve
FQDNs to IP addresses
64
LAN
DNS servers are a part of
All Internet-connected hosts.
65
LAN
Use the following command line tool to see all of the system's DNS servers
ipconfig /all

You can statically configure DNS and
still use DHCP for IP addressing
