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.

Open in ASN & BGP prefix lookup

Warning

10 of 23 announced prefixes have no ROA (RPKI not found): 46.175.16.0/21, 46.175.16.0/22, 46.175.16.0/24, 46.175.17.0/24, 46.175.18.0/24 (+5).

Without a ROA, networks cannot tell your routes from a hijack.

Fix: Create a ROA for each at your RIR portal, with origin AS34251 and a max length equal to the prefix length:

46.175.16.0/21 AS34251 max-length /21
46.175.16.0/22 AS34251 max-length /22
46.175.16.0/24 AS34251 max-length /24
46.175.17.0/24 AS34251 max-length /24
46.175.18.0/24 AS34251 max-length /24
46.175.19.0/24 AS34251 max-length /24
