What is is.
The IP address of the computer which made the request to the web server.
What it says.
It tells you from where the request has been made. The IP address
might be present in either
form. In either form, in consists of a
host and a
In the name form, the counprimers/try, and possibly the physical location can
be extracted, which is why the name form is more desireable.
What may cause trouble.
- Numerical addresses. The address might be in the
number form (as in
"22.214.171.124"). The domain name service (DNS) can be used to obtain the name
by resolving the address. I might happen though that resolution is not
possible at all.
- Proxies. Often requests are routed through
proxy servers before
they ever get to your web server. Though many individuals might access a web
site, requests may seem to come from only a couple of addresses, thas is,
those of the proxies. In this case, all original information on the address
- Non-country domains. Top level domains (TLDs) such as "com",
"net", "org", "gov", "mil" (and now "biz", "info" and others) don't indicate
the country of the address. In this case no information on location is
- Domain misuse. Some top level domains such "tv" (for "Tuvalu", a
Pacific island state) or "to" (for "Tokelau", ditto) have been misused because
the TLD suggests the address has something to do with television ("bbc.tv") or
makes for nice looking adresses ("www.go.to/hawaii/"). In these cases the TLD
does not really say something about the country.
