Chapter 5. TCP/IP (Transmission Control Protocol/Internet Protocol) Objectives 2.5 Identify the components and structure of IP (Internet Protocol) addresses (IPv4, IPv6), and the required setting for connections across the Internet 2.6 Identify classful IP (Internet Protocol) ranges and their subnet masks (for example, Class A, B, and C) 2.7 Identify the purpose of subnetting 2.8 Identify the differences between private and public network addressing schemes 2.9 Identify and differentiate between the following IP (Internet Protocol) addressing methods: 2.10 Define the purpose, function, and use of the following protocols used in the TCP/IP (Transmission Control Protocol/Internet Protocol) suite: TCP (Transmission Control Protocol) UDP (User Datagram Protocol) FTP (File Transfer Protocol) SFTP (Secure File Transfer Protocol) TFTP (Trivial File Transfer Protocol) SMTP (Simple Mail Transfer Protocol) HTTP (Hypertext Transfer Protocol) HTTPS (Hypertext Transfer Protocol Secure) POP3/IMAP4 (Post Office Protocol version 3/Internet Message Access Protocol version 4) Telnet SSH (Secure Shell) ICMP (Internet Control Message Protocol) ARP/RARP (Address Resolution Protocol/Reverse Address Resolution Protocol) NTP (Network Time Protocol) NNTP (Network News Transport Protocol) SCP (Secure Copy Protocol) LDAP (Lightweight Directory Access Protocol) IGMP (Internet Group Multicast Protocol) LPR (Line Printer Remote)
2.11 Define the function of TCP/UDP (Transmission Control Protocol/User Datagram Protocol) ports 2.12 Identify the well-known ports associated with the following commonly used services and protocols: 20 FTP (File Transfer Protocol) 21 FTP (File Transfer Protocol) 22 SSH (Secure Shell) 23 Telnet 25 SMTP (Simple Mail Transfer Protocol) 53 DNS (Domain Name Server) 69 TFTP (Trivial File Transfer Protocol) 80 HTTP (Hypertext Transfer Protocol) 110 POP3 (Post Office Protocol version 3) 119 NNTP (Network News Transport Protocol) 123 NTP (Network Time Protocol) 143 IMAP4 (Internet Message Access Protocol version 4) 443 HTTPS (Hypertext Transfer Protocol Secure)
2.13 Identify the purpose of network services and protocols (for example, DNS (Domain Name Service), NAT (Network Address Translation), ICS (Internet Connection Sharing), WINS (Windows Internet Name Service), SNMP (Simple Network Management Protocol), NFS (Network File System), Zeroconf (Zero configuration), SMB (Server Message Block), AFP (Apple File Protocol) and LPD (Line Printer Daemon)) What you need to know Understand IPv4 and IPv6 addressing Understand the function of default gateways Identify the function and purpose of subnetting Identify the differences between public and private networks Identify the function of protocols within the TCP/IP protocol suite Identify the ports associated with common network services Understand the function of various network services
