AS15055 YOURCOLO-ASN-1
Unclassified ARIN
Summary
YourColo
hosting business
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
/20announced 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
ASNinside 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
/20behind 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.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-20, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,779 prefixes, as published 2026-10-21. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
