My question is whether I can put a statement in .htaccess that will insure I receive IP addresses in my raw access log file.
I have a website on a shared hosting account. Recently, my account began providing hostname_lookup rather than raw IPs. The best information from the hosting company tech support is that if I put hostname deny statements (eg., deny someone.com), then my raw access logs will show hostname_lookup. I have a pretty long deny list, but I attempted as a test to remove all hostname deny statements. I still failed to get IP addresses. Maybe I have [still] overlooked an error, because among other things I found a deny statement I made that was "deny xxx-xxx-xxx-xxx" instead of "deny xxx.xxx.xxx.xxx". It's possible I have overlooked a similar statement.
It would be helpful if I could elicit IP addresses along with hostname_lookup. Hostname blocking can be more convenient than IP blocking. But, sometimes this is not useful. The reason is, a few of the hostname_lookup names are gibberish and the IP cannot be found by DNS lookup. So, I could end up trying to block an infinite number of hostnames.
Thank you for any help you can provide.
You can check HostnameLookups[1] in your apache config
