Common Misconception - IPv4 is Out of Address Space
NANOG Operational TTL Alert for 160-bit Headers (aka IPv4)
The 8-bit TTL field is reduced to 4-bits plus two 11 bits stuck at 1 for a long time
The new 8-bit fields are: SD11TTTT
Packets without the 11 will enter Deep Packet Inspection processing (slow)
SD are new Source and Destination Address bits set via the generic AAAA 128-bit records
4+8+12+30+6 = 60 + 68 = 128
VRHL+111.T1.000+Port12+30+Frag6
T1 sets the TTL bits - Use T0 at your own risk - VRHL=0101=5
