Of course! Including headers to show authenticity. I was very amused by the 
explanation of the "chicken and egg" problem. Who's creating that? The networks
who refuse to peer with non-peeringdb registered ASNs, or peeringdb who won't 
recognize ASNs that are not peering with anyone because nobody wants to peer 
with them because they are not registered in peeringdb because nobody wants to
peer with them? You get the idea.

Dear PeeringDB user,

Registering with peeringDB and peering negotiations are sort of egg and
chicken problem. We only want to have networks registered that already
do have settlement free peering.

After some basic checks it looks like you are only buying transit from 6939/Hurricane Electric, but are not connected to any Internet Exchange (e.g. AMS-IX/NL-ix) yet.

Having said this, is it acceptable to you to wait until you have your
1st settlement free peering setup? If you already have existing peering
sessions, please provide the following details to support your request for
peeringdb access:

Your AS number(s)
Which IXP / facilities you are peering at
Some of your peering partners (again AS numbers / name)

Please send your answers to support at or reply to this ticket.

Best regards,
PeeringDB admin on Duty
