AOL Proxy IP Addresses

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 Client IP Address Information

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:

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.
