7a. Why does the country section show only 100% unresolved?
Most likely because your web server is not doing name lookups and simply logging IP addresses. In order to determine the top level domain of the remote host, the program needs a resolved hostname, not an IP address. The simple fix is to just turn on name lookups on your web server so it starts logging names. Otherwise, you can pre-process your logs with something like the logresolve program supplied with apache or similar utilities, or you can use the Webalizers built in DNS lookup code (see 7b below).
7b. My Server doesn't do name lookups. Will The Webalizer?
Yes. Version 2.00 and higher supports reverse DNS support. See the DNS.README file for additional information. If you don't enable hostname lookups on your web server, you will get '100% Unresolved/Unknown' country totals. This is because your log files only have IP addresses and not names. While it is recommended that you let your web server handle the DNS lookups, DNS support can be used for those sites where DNS resolution is not an option.
