IP - This is a connectionless protocol, which means that a session is not created before sending data. IP is responsible for addressing and routing of packets between computers. It does not guarantee delivery and does not give acknowledgement of packets that are lost or sent out of order as this is the responsibility of higher layer protocols such as TCP. UDP - A connectionless, datagram service that provides an unreliable, best- effort delivery. ICMP - Internet Control Message Protocol enables systems on a TCP/IP network to share status and error information such as with the use of PING and TRACERT utilities. SMTP - Used to reliably send and receive mail over the Internet. FTP - File transfer protocol is used for transferring files between remote systems. Must resolve host name to IP address to establish communication. It is connection oriented (i. A MAC address is your computer's unique hardware number and appears in the form 0. A0- F1- 2. 7- 6. 4- E1 (for example). Each computer stores an ARP cache of other computers ARP- IP combinations. POP3 - Post Office Protocol. A POP3 mail server holds mail until the workstation is ready to receive it. IMAP - Like POP3, Internet Message Access Protocol is a standard protocol for accessing e- mail from your local server. IMAP (the latest version is IMAP4) is a client/server protocol in which e- mail is received and held for you by your Internet server. TELNET - Provides a virtual terminal or remote login across the network that is connection- based. The remote server must be running a Telnet service for clients to connect. HTTP - The Hypertext Transfer Protocol is the set of rules for exchanging files (text, graphic images, sound, video, and other multimedia files) on the World Wide Web. It is the protocol controlling the transfer and addressing of HTTP requests and responses. HTTPS - Signifies that a web page is using the Secure Sockets Layer (SSL) protocol and is providing a secure connection. This is used for secure internet business transactions. NTP - Network Time Protocol is a protocol that is used to synchronize computer clock times in a network of computers. SNMP - Stands for Simple Network Management Protocol and is used for monitoring and status information on a network. SNMP can be used to monitor any device that is SNMP capable and this can include computers, printers, routers, servers, gateways and many more using agents on the target systems. The agents report information back to the management systems by the use of . This trap information could be system errors, resource information, or other information. The SNMPv. 2 standard includes enhancements to the SNMPv. Get certified for Microsoft technology and products.

SMI- specific data types, such as including bit strings, network addresses, and counters. In SNMPv. 3 security was addressed. Because all of the trap information sent was in clear text, any monitoring information being sent and collected for operational purposes could also be pulled off the wire by a malicious person. SIP . Other feasible application examples include video conferencing, streaming multimedia distribution, instant messaging, presence information and online games. The protocol can be used for creating, modifying and terminating two- party (unicast) or multiparty (multicast) sessions consisting of one or several media streams. The modification can involve changing addresses or ports, inviting more participants, adding or deleting media streams, etc. RTP . RTP is used in conjunction with other protocols such as H. RTSP. IGMP . IP hosts and adjacent multicast routers use IGMP to establish multicast group memberships. IGMP is only needed for IPv. Updated: March 24, 2010. Applies To: Windows 7, Windows 8, Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows.IPv. 6 networks. TLS - Transport Layer Security is a cryptographic protocol that provides security for communications over networks such as the Internet. TLS and SSL encrypt the segments of network connections at the Transport Layer end- to- end. Several versions of the protocols are in wide- spread use in applications like web browsing, electronic mail, Internet faxing, instant messaging and voice- over- IP (Vo. IP).

Identify the Following Address Formats. IPv. 4 - Every IP address can be broken down into 2 parts, the Network ID(netid) and the Host ID(hostid). All hosts on the same network must have the same netid. Each of these hosts must have a hostid that is unique in relation to the netid.

We view IPv. 4 addresses in decimal notation such as 1. The following address ranges are reserved for private networks. IPv. 6 - The previous information on TCP/IP has referred to IPv. IP addresses due to the large influx of internet users and expanding networks. As a result, the powers that be had to create a new addressing scheme to deal with this situation and developed IPv. This new addressing scheme utilizes a 1. The hex address format will appear in the form of 3. FFE: B0. 0: 8. 00: 2: :C for example. The hardware is assigned a unique number by the manufacturer and the address is permanently assigned to the device. MAC Addresses are in a 4. They are used to uniquely identify a device on a network, and for other functions such as for being authenticated by a DHCP server. For more information, read MAC Addressing Formats And Broadcasts. Class A addresses are for networks with a large number of hosts. The first octet is the netid and the 3 remaining octets are the hostid. Class B addresses are used in medium to large networks with the first 2 octets making up the netid and the remaining 2 are the hostid. Class C is for smaller networks with the first 3 octets making up the netid and the last octet comprising the hostid. The Network ID and the Host ID are determined by a subnet mask. The default subnet masks are as follows. Class. Default Subnet. Subnets. Hosts Per Subnet. Class A2. 55. 0. 0. Class B2. 55. 2. 55. Class C2. 55. 2. 55. What if you wanted more than 1 subnet? Subnetting allows you to create multiple logical networks that exist within a single Class A, B, or C network. If you don't subnet, you will only be able to use one network from your Class A, B, or C network. When subnetting is employed, the multiple networks are connected with a router which enables data to find its way between networks. On the client side, a default gateway is assigned in the TCP/IP properties. The default gateway tells the client the IP address of the router that will allow their computer to communicate with clients on other networks. Classless addressing is referred to as Classless Inter- Domain Routing (CIDR) and is done by allocating address space to Internet service providers and end users on any address bit boundary, instead of on 8- bit segments. So 1. 72. 1. 6. 5. Class B address space and which also puts it on the same network as 1. Instead, by using classless addressing 1. Using a device (such as a router) or piece of software that implements NAT allows an entire home or office network to share a single internet connection over a single IP address. A single cable modem, DSL modem, or even 5. Additionally, NAT keeps your home network fairly secure from hackers. NAT is built in to the most common Internet Connection Sharing technologies. It allows a single public IP address to be used by many hosts on a private network. SNAT is done through one to one IP address translation of one internal IP address to one external IP address where NAT is effectively one external address to many internal IP addresses. When a client is configured to receive an IP address automatically, It will send out a broadcast to the DHCP server requesting an address. The server will then issue a . Some of the benefits of DHCP include the following. Prevents users from making up their own IP addresses. Prevents incorrect gateway or subnet masks from being entered. Decreases amount of time spent configuring computers especially in environments where computers get moved around all the time. APIPA . Client systems that are configured for automatic IP address assignment / dynamic IP assignment will attempt to use DHCP to make a request for an IP address lease for a given network. When the DHCP server is unavailable the service on the client will automatically configure the system with an APIPA IP address in the 1. This type of network transmission is used where a private or unique resource such as media servers are being requested for two way connections that are needed to complete the network communication. So in the media server example, a client system may make the request for streaming content from the single source and the responding system may leverage unicast as part of the response to the session request to deliver the content. In a media server example, the single source address may need to send the data to multiple clients; it does this by sending the data with multiple destination IP addresses. All the clients that . If it is not the client does not receive the data. If a network node does see that the data is intended for them the device will respond by receiving the packet. The network node that is sending the traffic will use the broadcast address for that subnet and every device in that broadcast domain will receive the broadcast information. Generally the broadcast address is the last IP address of that segment.
