Yes! We are now offering 1-year
Autodesk Subscriptions on the Store when you purchase your
software. The Autodesk Online Store does not yet sell
subscription contracts by themselves for the Autodesk products
you may already own, nor renewals of your current
subscriptions. If the Subscription Program is available for
your product, and you chose not to buy a subscription from the
Store at that time, you can still 'attach' a subscription
within 30 days of purchasing from the Store by contacting your
local Autodesk
Authorized Reseller. The Autodesk Authorized Reseller
can also provide information about available training
services. Your confirmation email is your proof of purchase.
For more information about our Subscription Program, visit our
Subscription
Center.
Also, I don't think you can buy a network license.
