DNS Lookup

Log files contain information about user hosts. It may be either a domain name or an IP address. For example 65.94.232.43 is an IP address of the user. We can resolve this IP address (do DNS lookup or, more accurate, reverse DNS lookup) and determine that this address corresponds to mtl-hse-ppp202789.qc.sympatico.ca. WebLog Expert uses domain names to determine top-level domains.

In some cases IP addresses are already resolved in the log files. But usually they are not. WebLog Expert has a capability of resolving IP addresses. If this option is set to ON in the profile the program will do DNS lookups before analyzing logs. You must be connected to Internet during DNS lookup.

Some IP addresses don't have corresponding domain names so there may be IP addresses shown in the reports even with the Lookup DNS Names option enabled.

The program uses multiple threads to perform the DNS lookups. The program also caches the lookups. So if the program needs to resolve the IP name that is always in cache it won't need to repeat the DNS lookup.

You can use the DNS Lookup category of the Options dialog to specify various lookup options.
