IPv4; what is it ______ what is the bit-value _______
The most common type of IP address; officially called IPv4 but simplified to *IP*. (b) it has a 32-bit value broken down into 4 groups of 8-bits separted by DOTS.
Example: 192.168.4.2 is called IPv4 __________ also referred as _________
The IP Address of the ROUTER'S connection to your LAN.
IANA
Internet Assigned Numbers Authority. Formed to track and disperse IP addresses until 1998 by Jon Postel. I grew quickly and so the (RIRs) Regional Internet Registries takes care of those duties
CIDR
Class-less Inter-Domain Routing
What is a SUBNET MASK
Is a string of 1's; followed by a string of 0s; 32-bit long (4 bytes)
The cornestoen of SUBNETTING is the ________ You take an existing /8 /14 /24 SUBNET and EXTEND the SUBNET MASK by adding _________
(a) SUBNET MASK (b) More 1s and taking away the same number of 0s
BOOTP is common on _________ and __________ systems
(a) UNIX/Linux (b) Macintosh
APIPA
Automatic Private IP Addressing. This system generates IP addresses if there is no response to a DHCP discovery message.
Special TCP/IP address: 127.0.0.1
LOOPBACK ADDRESS. To send packets to itself. (PING)
What IP address is PING
127.0.0.1 To test a NICs capability to send and receive packets.
10.0.0.0 through 10.255.255.255
Private IP addresses (1 Class A license)
172.0.0.0. through 172.31.255.255
Private IP addresses (16 class B licenses)
192.168.0.0. throught 192.168.255.255
Private IP addresses ( 256 Class C licenses)
The first 64-bits of a LINK-LOCAL ADDRESS is always
FE80::/64 = FE80:0000:0000:0000
IPv6 Addresses consists of
8 Groups of 4 Hexadecimal characters each or 16-bits each for a total of 8 x 16-bits = 128-bits long. E.g. 2001 : 0000 : 0000 : 3210 : 0800 : 200C : 00DF : 1234. *2001hx*=0010 0000 0000 0001 = 16-bits
