_Standard:IPv2

InZernet Protocol version 2

IPv2 builds on top of Ethernet. An IPv2 packet looks like:

Version	Traffic Class	Next Header	Hop Limit	Source Address	Destination Address	Payload
Version of the IP packet	Differential services	Specifies type of next header	Value decremented by one at each intermediate node visited by the packet.	Source	Destination	The data

Values for Version

Value	Description
1	For IPv1 (deprecated) and only works on CC
2	By default, this is used

Values for Traffic Class

Best effort is used by default. Unless there is a lot of congestion, packet is likely to end up to the destination.

Value	Meaning	Description	Drop Probability
0 (Default)	Best effort	Tries to deliver the packet as best as possible	N/A
46	Expedited forwarding	Delivers the packet as fast as possible	N/A
10	Priority Latency	Focuses on low latency. Will drop if latency is high. Expedited forwarding packets have higher precedence over Priority Best effort	Low
12	Priority Through	Focuses on delivery. Does not drop but Expedited forwarding has precedence	Medium
18	Immediate Latency	Focuses on low latency. Will drop if latency is high. Priority packets have higher precedence over Immediate and Best effort	Low
20	Immediate Through	Focuses on delivery. Does not drop but Priority and Expedited forwarding has precedence	Medium

Values for Next Header

Code	Keyword	Protocol
1	ICMP	Internet Control Message Protocol
3	GGP	Gateway-to-Gateway Protocol
6	TCP	Transmission Control Protocol
17	UDP	User Datagram Protocol

Values for Hop Limit

Values can be anywhere from 0 to (infinity). We recommend at least 64. (Please don't put over 255+, I really doubt your network is that big)
