 |
|
| Is it possible to log the visitors domain names instead of their IPs to access.log? |

Impossible, as not all visitors are domain names. You can do a reverse dns check on the IP to see if it resolves to a domain name though.

| No its not impossible - just a question of Aprelium have a way to do it now or it has to be compiled into the code first. |

How can you assign a domain name to someone who has a regular internet connection and doesn't run any websites?

No it's not impossible. You can do a "reverse DNS" lookup on the IP address, for instance mine is similar to this:
cpc2-swin5-0-0-cust000.brhm.cable.ntl.com

It's time consuming and not all IP's have a valid reverse DNS configured. Would be a performance hit. Best left to log file analyser utilities...

I know thats possible, but who would want to know the reverse DNS for every record in their log?

I know it's not always possible and very time consuming, however I was correcting the wrong info stating it was impossible. What might have been better to state is that it's unpractical.

You should use a Web Log Analyzer to do a reverse DNS lookup. You will be
able to see their IP's as domains if you do that.
Here's a few log Analyzers that may be able to do this.
Funnel Web Analyzer

Weblog Expert

I meant it would be impossible to implement it into Abyss because it didnt always work, but I didn't state that.

You can also use tracert at the cmd prompt to do it. Although as stated, no all IP's have a reverse DNS.

You can post process the log file using a tool which will replace IPs with their domain names (if possible).

We already have a payed weblog analyzer but it doesn't do reverse DNS of the log file. We use to run Apache which have reverse DNS. My boss wanted to see which countries people where coming from. So that's why I asked. |

bean,
Even on Apache, reverse DNS lookups are not recommended because they are a performance hog: http://httpd.apache.org/docs/1.3/mod/core.html#hostnamelookups reads:
| Quote: | | The default for this directive was previously on in versions of Apache prior to 1.3. It was changed to off in order to save the network traffic for those sites that don't truly need the reverse lookups done. It is also better for the end users because they don't have to suffer the extra latency that a lookup entails. Heavily loaded sites should leave this directive off, since DNS lookups can take considerable amounts of time. The utility logresolve, provided in the /support directory, can be used to look up host names from logged IP addresses offline. |

I found the website I was originally looking for. It's ClustrMaps. It works a lot like Gvisit.
