Header Info
AOL Members' requests for internet objects are usually handled by
the AOL Proxy system. When a member
requests multiple documents for multiple URLs, each request may come
from a different proxy server. Since one proxy server can have multiple
members going to one site, webmasters should not make assumptions about
the relationship between members and proxy servers when designing their
web site.
The proxy addresses are listed in the table below. If you want to
identify the proxy requests from AOL accessing your site, examine your
logs and count the requests that come from one of the IP networks
listed below or from the .proxy.aol.com domain. If you want to count
all of the requests that originate from the aol.com domain, then
include the addresses of the AOL clients as well as those of the
proxies.
AOL members are assigned a dynamic IP address that is used for all
requests not handled by the AOL proxy system. These IP addresses can be
used to identify AOL members making requests to your site.
It is a common mistake to deny AOL members access to a site because
of confusion about the IP space designated as private network space.
According to Address Allocation for Private Internets or RFC 1597
only these IP ranges are designated for private networks:
10.0.0.0
172.16.0.0
192.168.0.0 |
-
-
-
|
10.255.255.255
172.31.255.255
192.168.255.255 |
As you can see by the list below, AOL members will often be assigned
a 172.128.X.X IP address. If you believe AOL members are unable to
reach your site, check your firewall and routing rules to make certain
you are not blocking AOL traffic or routing it back inside your private
network.
