Display - US IP Targetting : ADTECH vs DFA
We use ADTECH as our display ad server and our company has a global portfolio of publisher sites.
Our instance of ADTECH is based out of Germany and is not a US instance of ADTECH - http://adserver.adtech.de
Recently we have had a number of US agencies complain that their US IP targeted campaigns are being delivered outside US IPs based on their figures from DFA.
The issue has been reported across more than 1 website and more than 1 advertiser / agency
Has anyone else experienced reporting geo reporting discrepancies between ADTECH and DFA in US or other countries?
I appreciate there may be some differences but the magnitude of the discrepancies US agencies are reporting to us are too great to be insignificant
