isp hosting business

One address answers with a placeholder domain, another announces itself as the broadcast address.

What it's used for

  • A regional provider and hosting operator. 8,192 addresses across seven IPv4 prefixes, the IPv6 block 2602:fff8::/36, and four observed BGP neighbours.

Notable

  • 198.251.116.0 answers domain.com, a placeholder rather than a hostname.
  • 65.112.28.255 answers broadcast.officialnameserver.net, naming the address's role in the block.
  • 65.112.28.0/23 is netname QWEST-63-112-28-0, whose first octet is two lower than the block's.
  • Three blocks are netname SPRINTLINK but registered to a different company entirely.
  • A fourth carries the legacy chain CENTURYLINK-LEGACY-QWEST-INET-109.
  • Names appear under five unrelated domains, including one naming an application and a database instance.
  • One block's registry lookup failed and returned nothing.

Interesting

  • A netname one octet off from the block it describes is the same class of error as a mistyped address, and it survives because nothing checks netnames against the ranges they sit on.
  • Five registrants, five domains and three legacy carrier names in one small AS is what a network looks like after years of buying blocks wherever they came up. Each piece keeps the naming of whoever configured it, and no later owner has reason to normalise any of it.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, 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 1,783 prefixes, as published 2026-10-17. 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.
