Why are you trying to do a zone transfer from my domain?
The zone transfer is an integral part of performing the RIPE NCC Region Hostcount. It is performed once at the end of each month for the purpose of generating summary statistics about the growth of the Internet.
The RIPE NCC apologises for any concern that may have been caused by an unexpected attempt at a zone transfer. We would be extremely grateful if you would enable zone transfers for requests originating from the address range 18.104.22.168/22.
If you have further questions or concerns, please contact: firstname.lastname@example.org.
