About this network

Thirty-four IPv6 announcements that tile one allocation at ten different lengths.

What it's used for

• A data-centre operator's network. Seventy-three IPv4 prefixes and thirty-four IPv6 prefixes announced from the United States, with sixteen observed BGP neighbours.

Notable

• The IPv6 announcements start at 2607:9800::/33 and descend through /35, /40, /45, /47, /46, /44, /43 and /42, each one carving a piece out of the block above it.
• The netname NET-67-23-160-0-1 sits on three separate blocks, only one of which is the address it names.
• Several announced blocks are registered to other companies entirely, under netnames such as JADASE-BLK1 and CUMULUS.
• One netname, IMMEDION-CVG-209-173-128-0-1, carries the operator's own name while the registrant field names a different company.
• Eight of eighteen sampled addresses answered, across five unrelated domains, and three of those answers were the identical name ip.immedion.net.

Interesting

• The IPv6 cascade is the find. Announcing a covering prefix and then a ladder of more-specifics inside it is how a colocation provider hands blocks to tenants that want their own routing, and it is visible here as pure arithmetic in the prefix list.
• Five domains across eight answers is the signature of shared space: the addresses belong to the operator, the names belong to whoever rents them, and the registry only records the first half.
• Three addresses answering with one name means the reverse zone identifies the network, not the host.
