The log file that host name was recorded in place of a host IP address

Can I use a log file that ‘host name’ was recorded in place of ‘host IP address’?
A host is displayed with “0.0.0.0” in a visitor profile when I import such a log file by import_logs.py.

Hi, I don’t think so because IP addresses are resolved to a host in a separate step from the import. They are assumed to be a valid IP address, else they are turned to unknown (0.0.0.0).
