AS15055 — YOURCOLO-ASN-1

AS15055 announces 1 IPv4 prefixes covering 4,096 addresses and 0 IPv6 prefixes.

About this network

Both identifiers carry a counter, and neither counts to more than one.

What it's used for

• A colocation provider's network. A single IPv4 /20 announced from the United States, no IPv6, and one observed BGP neighbour.

Notable

• The one block is registered to the holder under the netname YOURCOLO-NETBLK-02, numbered two despite being the only block in the inventory.
• The AS handle is YOURCOLO-ASN-1, which spells the record type inside the AS handle and then numbers it.
• The routing history begins in 2007.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• Two identifiers, two counters, and nothing to count. The netname's number implies a first block that is not announced here, either returned, never routed, or held for something else. The handle's number implies a second AS that does not exist.
• Spelling ASN inside an AS handle is redundant by construction, and it recurs often enough in this range to look like a habit rather than a mistake: the field's own name already says what it holds.
• A /20 behind a single upstream is a lot of address space on one path. For a colocation business that is a real exposure, since everything hosted inside it shares the fate of that one connection.
• The provider publishes no reverse names at all for the sampled addresses, which for a hosting network leaves customers to set their own or go without.
