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, 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
