Things to know for the IPv6 Test
- Goals
- Addresses
- An IPv6 address is 128 bits long
- It has three parts
- Headers
- Normal header has few fields, but more bits that IPv4
- Uses optional headers for things like
- TCP
- UDP
- Jumbograms (very large packets)
- Every header says if intermediate routers need care (most say
no)
- Easy to add new headers
- Conversion
- Almost all OSs can do IPv6 including OS X, Windows NT, Linux,
Cisco, etc.
- For every IPv4 address there is an IPv6 address, but not the
other way round
- All applications that deal with IP numbers must be re-written
- One can connect to IPv6 via
- Internet2
- Tunnelling
- Other national solutions (even Thailand has one)
- Other
- No fragmenting by routers
