AS14532 — CBOSS

AS14532 announces 3 IPv4 prefixes covering 1,024 addresses and 4 IPv6 prefixes.

About this network

Five IPv6 announcements and a single upstream to carry all of them.

What it's used for

• A payments and hosting company's network. 1,024 IPv4 addresses across three prefixes, five IPv6 prefixes, and one observed BGP neighbour.

Notable

• The IPv6 blocks come from two unrelated ranges: three scattered end-site blocks including 2605:3380:4301::/48, plus 2607:abc0::/47 and 2607:abc0:2::/48 from a second range.
• Those last two overlap in coverage, with the larger announcement spanning two blocks and the smaller sitting immediately beyond it.
• All three IPv4 blocks carry the netname CBOSS-IPV4-1, which names the protocol and implies a companion record.
• Nine addresses were queried for reverse DNS and none returned a name.

Interesting

• Announcing three consecutive end-site blocks as one larger prefix and a separate smaller one is a choice, not a necessity. Combining all three into a single announcement would need the run to start on the right boundary, and it does not, so the routing table carries two entries where the address space suggests one.
• Five IPv6 announcements against three IPv4 blocks is an unusual balance for a network this size, and the scattered end-site blocks in the first range suggest space collected one request at a time rather than allocated in a plan.
• One observed neighbour carrying eight announcements is the thinnest ratio of upstreams to prefixes in this range, and it means a single carrier relationship decides whether any of it is reachable.
• The netname naming a protocol is a small piece of foresight from an operator that expected to hold both kinds of space, which the IPv6 side confirms.
