Configuring a Network Connection LO 10.1

Understanding the TCP/IP Protocol Suite Set of rules formalized in a standard Protocols define software used in networking Software must work together Software bundled together in a protocol stack TCP/IP is the most important protocol stack

The TCP/IP Protocol Suite Suite of many protocols that work together Protocol suite of the Internet and private networks Two core protocols Transmission Control Protocol (TCP) Internet Protocol (IP)

Transmission Control Protocol (TCP) Manages accurate delivery of messages Verifies and resends pieces that fail to reach destination TCP has several subprotocols

Why IPv6 is Better than IPv4 IPv6 has many more addresses Has Mobile IP for mobile devices Automatically assigns addresses to devices Manages addresses better than IPv4 Subprotocols provide better security

IP Addressing Fundamentals IP address assigned to a network adapter Modem (cable, DSL, or analog) has address Subnet mask applied to IP address Routing protocols determine how to send packets Globally unique IP address for each Internet device

IPv4 Addresses In use for three decades 32-bit addressing (232) 4.3 billion possible IP addresses Allocation methods reduced usable addresses Four parts in dotted-decimal format (192.168.1.134) Each part is within 0 to 255 range Last IPv4 block assigned on February 1, 2011

IPv6 Addresses Internet transitioning to IPv6 New addressing scheme with many more addresses Manufacturers and standards orgs preparing 128-bit addressing (2128) Eight groups of hexadecimal numbers Groups separated by colons

IPv6 0010000000000010 0000010001110000 1011100011111001 0000000000000000 0000001000001100 0010100111111111 1111111001010011 0100010111001010

Which Addresses Can You Use? Public addresses Assigned to hosts on the Internet Must be unique on the entire Internet Internet Assigned Number Authority (IANA) Private Addresses

Table 10-1 IPv4 Private IP Address Ranges Private IPv4 Address Ranges 10.0.0.0 through 10.255.255.255 172.16.0.0 through 172.31.255.255 192.168.0.0 through 192.168.255.255

How does a NIC get an address? Static Address Assignment Automatic Address Assignment Automatic IP Addressing (Using DHCP) Automatic Private IP Address Assignment (APIPA)

Connecting to the Internet LO 10.2

Internet Connections Wide Area Network (WAN) Internet Service Provider (ISP) Computer-to-Internet versus LAN-to-Internet

Connecting to the Internet

Dial-Up Connections Using Analog Modems Use traditional phone system Inexpensive WAN option 56 Kbps Need ISP service Cannot use voice and data on same line

Wired Access Integrated services digital network (ISDN) Digital Subscriber Line (DSL) Cable

Connecting to a WWAN

Connecting to a Satellite WWAN

Wireless LAN (WLAN) Connections Wi-Fi Standards IEEE 802.11a, 802.11b, 802.11g, 802.11n, and 802.11ac Max distance a few hundred feet Does not connect directly to an ISP Connects via router to WAN to ISP to Internet Newer standards faster and more secure

Using a Virtual Private Network (VPN) A simulated private network inside a “tunnel” Connect to a remote access VPN Site-to-site VPN Each data packet encapsulated Secure by encrypting data before encapsulating Secure with authentication at both ends

Sharing Files and Printers LO 10.4

Server Side of File and Printer Sharing File and printer sharing service A share is a shared folder or printer Share and disk folder are separate entities Service installed and enabled by default
