This may necessitate restarting the execution of the program at the destination host.

Once the message was delivered to the destination host, an acknowledgement was delivered to the sending host.

Z (communication with destination host administratively prohibited)

T (for this ToS the destination host is unreachable)

The protocol (network layer) address is that of the destination host.

The server decrypts the data, and then directs it to the destination host and port.

The IMP routes the message to the destination host using protocols that were eventually adopted by Internet routers.

A hop count of n means that n gateways separate the source host from the destination host.

ACLs can also restrict the establishment of a link depending on the destination host being contacted and the host trying to establish the connection.

The server should resolve the domain name and make connection to the destination host if it can.
