Peakhour is a reverse proxy and therefore sits between your website and your end client. Once you have successfully pointed your domain to Peakhour, your website will only be receiving visits from Peakhour IP addresses. If you wish to preserve the IP addresses of visitors in your access logs you will have to configure your server to check the

X-Peakhour-IP

header to retrieve the IP of the request coming into Peakhour. Please note that depending on your web server the configuration to use this header in your logs will be different.
