| Question | Answer |
|---|---|
| Dotted decimal | A common format for the decimal equivalent of a 32-bit IP address |
| downloadable workspace | A portable, custom work environment available to the user no matter where the user logs in. |
| Flow level | A designation for an IPv6 datagram specifying special handling or a special level of throughput |
| hop limit | The number of remaining router hops a datagram can take before it's discarded. Specified in the IPv6 mail header and decremented at each router. |
| IPv6 | A new standard for IP addressing that features 128-bit IP addresses. The intent of IPv6 designers is to phase it in gradually over the next several years. Also called IPng (next generation) |
| Jumbo Payload | A datagram payload with a length exceeding the conventional limit of 65, 535 bytes. IPv6 enables jumbo payload datagrams to pass through the network |
| Payload length | The length of the data portion of an IPv6 header (excluding the header itself) |
| IPv6 address characteristics | 128-bit address consisting of eight colon-separated groups of four hexadecimal digits with leading zeros omitted. You can also eliminate multiple consecutive blocks of zeros and replacing them with a double colon (Only once). |
| Example of IPv6 address: 2001:0DBB:CD30:0000:0000:0000:0055/60 | using shortcuts: 2001:DBB:CD30::55/60 |
| arp | A utility that configures and displays the contents of the Address Resolution table (ARP table) Use -a option to see table. |
| file transfer protocol (FTP) | A client/server utility and protocol that uses TCP at Transport layer, used to transfer files between two computers. Can create and remove directories and display contents of directories as well. Username is usually anonymous. |
| Hostname | A utility the outputs the hostname of a local host. |
| ifconfig | Linux/UNIX utility that displays TCP/IP configuration information |
| ipconfig | Windows utility that displays TCP/IP configuration information such as your IP address, MAC address, subnet mask, default gateway, DNS server address(es). Use the /all option to see all information. Can also used to release and renew DHCP IP address. |
| nbtstat | A utility that provides statistics and other diagnostic information on NetBIOS over TCP/IP |
| netstat | A utility that provides statistics and other diagnostic information on TCP/IP protocols |
| Network sniffer | A class of dianostic applications or hardware devices that can capture and display the contents of datagrams. Also called a protocol analyzer. |
| Network File System (NFS) | NFS allows the user on an NFS client computer to access files located on a remote NFS server tranparently |
| ping | A diagnostic utility that tests connectivity with another host. |
| Remote copy (rcp) | UNIX-based utility allows you to copy files between computers using syntax similar ot the UNIX cp command. Does not require user to log in prior to intitiating the file copy process |
| Secure copy (scp) | A secure version of rcp that provides data encryption through SSH |
| Secure File Transfer Protocol (SFTP) | A secure version of FTP that provides data encryption through SSH |
| Server Message Block (SMB) | Application layer protocolthat enable Windows clients to access network resources such as files and printers |
| route | A utility that displays the router path a packet takes from its source to its destination |
| traceroute | A UNIX/Linux utility that displays the router path a packet takes from the source to the destination (tracert in Windows operating systems) |
| Trivial File Transfer Protocol (TFTP) | A UDP based client/server utility and protocol used for simple file transfer operations. |
