SPN for network service

The HOST service represents the host computer. The Kerberos protocol uses the HOST SPN to access the host computer. The Kerberos protocol uses the long-term key on the host computer to create a service ticket.
The HTTP service class is one of the built-in services that act as an alias to the HOST SPN. The HOST SPN is mapped to the host computer account. Therefore, when you use the default HTTP service class, the Kerberos protocol uses the computer account as the service account to request a service ticket.”

Translation – if you are using network service and tying to set the SPN – use the computer name as the account name.
