Whythisdifference?

• Earlyadoptersvslateradopters– LateradoptersdonothaveabroadbaseofIPv4installation,andhavebeenpushedintousingIPv6asthecommoninfrastructurewithNAT64edges(Jio inIndiaisagoodexample)

– EarlyadoptersarenotforcedintoIPv6andcanwait• CarriageEconomics– TheeconomicreturnsindeployingIPv6acrossanIPv4infrastructuredonotgeneratenewrevenues,norgenerateoperationalsavingsorgeneratesupplyefficiencies

– Thereisno“adoptionpull”effectinIPv6

Whydoitatall?
