Incorrect GeoIP filtering of 185.83.72.0/22
Hello, We are reaching out to NANOG since the following issue is mostly observed in US-based service providers. We are advertising the prefix *185.83.72.0/22 <http://185.83.72.0/22>*, that seems to be blocked by various popular US-based services, thus our customers originating from this prefix have trouble reaching such services. Indicatively: Atlassian (AMAZON), Adobe (AKAMAI) . To the best of our understanding, the blocking is enforced due to US / EU sanctions against Iran. The prefix was purchased by us - Lamda Hellix SA ( *AS56910* based in *GREECE, EUROPE* ) - approximately 8 months ago. We followed the necessary process as instructed by RIPE for changing the ownership of the prefix. Therefore, we kindly ask those of you that use/maintain/operate GeoIP databases to update your records. Most importantly, we would be grateful if you could share with us ( net@lamdahellix.com) which Geo databases are mainly used in the US for this purpose. Kind regards, Adam Pavlidis
Adam, ip2location.com has that IP block listed as "(DCH) Data Center/Web Hosting/Transit” which we’ve seen cause issues for residential users in the past, most notably on Cogent IP space. We worked with support@ip2location.com to have the address block re-analyzed and updated to "(ISP) Fixed Line ISP” which resolved many of the issues users had accessing various streaming CDN services.
