|
No connection with the destination is established before sending data packets. |
Connectionless |
|
|
IP is inherently unreliable because packet delivery is not guaranteed. |
Best Effort |
|
|
An operation that is independent of the medium carrying the data. |
Media Independent |
|
|
In some cases, an intermediate device, usually a router, must split up a packet when forwarding it from one medium to another medium with a smaller MTU. This process is called ______. |
Fragmenting |
|
|
This part of the IPv4 (and IPv6) header contains a 4-bit binary value set to 0100 that identifies this and an IPv4 packet. |
Version |
|
|
This part of the IPv4 header is an 8-bit field that is used to determine the priority of each packet. |
Differentiated Services or DiffServ (DS) |
|
|
The six most significant bits on the DiffServe (IPv4 header) is called the ___. |
Differentiated Services Code Point (DSCP) |
|
|
The last two bits on the DiffServe are called the ____ bits. |
Explicit Congestion Notification (ECN) |
|
|
The IPv4 header that contains an 8-bit binary value that is used to limit the lifetime of the packet. |
TTL (Time to Live) |
|
|
The IPv4 header field used to identify the next level protocol. Common values include ICMP, TCP, UDP. |
Protocol |
|
|
The total length of the header checksum fields and are used to identify and validate the packet. |
The Internet Header Length (IHL) |
|
|
This IPv4 header field identifies the priority of each packet. |
Differentiated Services |
|
|
IPv6 is based on a ___ bit hierarchal addressing as oppose to IPv6, which is based on a ___ bit. |
128 |
|
|
IPv4 is how many octets? |
20 |
|
|
IPv6 is how many octets? |
40 |
|
|
This IPv6 packet header is an 8-bit field equivalent to the IPv4 differentiated services (DS) field. |
Traffic Class |
|
|
This IPv6 header field suggests that all packets with the same flow label receive the same type of handling by routers. |
Flow Label |
|
|
This IPv6 header field indicates the .length of the data portion of the payload of the packet |
Payload Length |
|
|
This IPv6 header field is equivalent to the IPv6 protocol field. It indicates the data payload/application type that the packet is carrying. |
Next Header |
|
|
This IPv6 field replaces the IPv6 TTL field. The value is decremented by a value of 1 by each router that forwards the packet. |
Hop Limit |
|
|
An IPv6 packet may contain this header, which provides option network layer information. |
Extension Header (EH) |
|
|
Unlike IPv4 routers do no ___ routed IPv6 packets. |
Fragment |
|
|
Host on a remote network that does not share the same network address. |
Remote Host |
|
|
A host can ping itself with what IP address. |
127.0.0.1 |
|
|
The command to display the host routing table on the |
asd |
