Network report
Who holds an IP address, prefix or AS number, how it is routed (origin AS, RPKI, IRR), its reverse DNS, blocklist listings and PeeringDB record, with what to fix first.
Checking routing, RPKI, reverse DNS, blocklists and the registry. This usually takes 3 to 10 seconds.

What to fix
-
Warning
No IPv6 prefixes announced.
Networks without IPv6 force their users through NAT64 or leave them unreachable from IPv6-only networks.
Fix: Get an IPv6 allocation from your RIR (usually free with your IPv4 membership) and announce it.
-
Warning
No IRR as-set is listed.
Peers and route servers build prefix filters from the as-set. Without one they fall back to the AS number alone, which breaks as soon as you have customers.
Fix: Create an as-set in your RIR’s IRR database and add it to your PeeringDB record.
