Exam 4: Introduction to TCP/IP Protocols
Describe the size differences in IPv4 and IPv6 IP addresses.
(32) 
VerifiedThe most notable difference between IP addresses in IPv4 and IPv6 is their size. While IPv4 addresses are composed of 32 bits, IPv6 addresses are composed of eight 16-bit fields, for a total of 128 bits. The added fields and the larger address size result in an increase of 296 (or 4 billion times 4 billion times 4 billion) available IP addresses in the IPv6 addressing scheme. The addition of more IP addresses not only allows every interface on every Internet-connected device to have a unique number, but also eliminates the need for IP address conservation. With the increasing number of network-enabled devices, including handheld computers, telephones, home security systems, traffic cameras, and even pet tracking systems, the limited quantity of IPv4 addresses posed a serious bottleneck.
A(n) ____ address represents any one interface from a group of interfaces, any one of which can accept a transmission.
(28) VerifiedA
____ is more efficient than TCP for carrying messages that fit within one data packet.
(39) VerifiedB
____________________ is a process of subdividing a single class of networks into multiple, smaller logical networks, or segments.
(40) TCP ensures reliable data delivery through sequencing and ____________________.
(39) In IPv4 addressing, each IP address is a unique ____ number.
(37) The format of ARP tables is the same from one operating system to another.
(37) ____ ARP table entries are created when a client makes an ARP request that cannot be satisfied by data already in the ARP table.
(35) If the standard port number for the Telnet service is 23, a host whose IPv4 address is 10.43.3.87 has a socket address for Telnet of ____.
(32) ____ is a terminal emulation protocol used to log on to remote hosts using the TCP/IP protocol suite.
(30) In the TCP/IP protocol suite, ____ is the core protocol responsible for logical addressing.
(30) ____ is a simple Application layer protocol used to synchronize the clocks of computers on a network.
(40) In the domain name www.google.com, ____ is the top-level domain (TLD).
(31) In IPv4 addressing, explain what is special about an address containing 127 in the first octet and how this address is used in troubleshooting.
