Autonomous system
AS15718 FL-749-15718
Unclassified ARIN
Summary
FROSTWEB
hosting business isp
The handle is a serial number ending in this network's own AS number.
What it's used for
- A hosting company's network. One IPv4
/23announced from the United States, no IPv6, five hundred and twelve addresses, through a single observed BGP neighbour.
Notable
- The AS handle is three parts joined by hyphens: two letters, a three-digit number, and this autonomous system's own number.
- The holder string is that same handle, a spaced hyphen, then the company name, so the code appears before the name it belongs to.
- The single block's netname is the same code with the AS number removed, leaving the letters and the three digits.
- The only registrant is the company. No abuse role and no technical contact are listed.
- Five hundred and twelve addresses are announced as one route behind one neighbour.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- A serial code as an identifier is a filing system leaking into public view. The letters and digits mean something to whoever assigned them and nothing to anyone reading the record, which is the opposite of what a name field is for.
- Stripping the AS number from the netname is the one considered part of this record. The block outlives any particular routing arrangement, so the number does not belong on it, and someone knew that.
- One block, one route, one upstream and one contact is the smallest complete network there is.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, 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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
