Dormant space on blacklists, how can I resolve this?

Thu Apr 27 13:46:04 UTC 2023

Hello,

I run Crocker Communications (AS7849) and have ARIN allocations of 161.77.0.0/16 & 66.59.48.0/20.   The 66.58.48.0/20 space was used for our datacenter which shutdown a couple years ago.  The space has mostly been dormant for the past couple years.   I’m now starting to assign 66.59.[55-60].0/24 to a new group of residential FTTH customers.   The customers are getting access denied messages from Akamai based websites.

What can I do to get Akamai to unblock the 66.59.48.0/20 space.
Is there a website I can look to research the reputation of the subnets?  They haven’t been used in years so I would expect them to be pretty clean.

Thanks

-Matt
