NET1L - Lesson 8 (Network Layer Pt.2)

IPv6 was developed by ____________.

• Internet Engineering Task Force (IETF)

• Institute of Electrical and Electronics Engineers (IEEE)

• International Organization for Standardization (ISO)

IPv6 does not overcome the limitations of IPv4.

• True

• False

Improvements that IPv6 provides:

• Increased address space

• Improved packet handling

• Eliminates the need for NAT

• Eliminates addressing

Based on 128 bit address, not 32 bits.

• Increased address space

• Improved packet handling

• Eliminates the need for NAT

Simplified header with fewer fields.

• Increased address space

• Improved packet handling

• Eliminates the need for NAT

Since there is a huge amount of addressing, there is no need to use private addressing internally and be mapped to a shared public address

• Increased address space

• Improved packet handling

• Eliminates the need for NAT

There are 340 undecillion IPv6 addresses.

• True

• False

Significant fields in the IPv6 header:

1. Version

2-6. ????????????

7. Source IPv4 Address

8. Destination IPv4 Address

• Traffic Class

• Flow Label

• Payload Length

• Next Header

• Hop Limit

[IPv6 Packet Header]

This will be for v6, as opposed to v4

(4 bit field = 0110).

• Version

• Traffic Class

• Flow Label

• Payload Length

• Next Header

[IPv6 Packet Header]

Used for QoS.

Equivalent to DiffServ – DS field.

• Version

• Traffic Class

• Flow Label

• Payload Length

• Next Header
