Summary

United States · AI-generated

isp hosting business

A sole proprietorship with one upstream, three registrants and a /40 of IPv6.

What it's used for

  • A small United States internet provider held by a sole proprietorship registered in a person's own name. 1,536 addresses across five IPv4 prefixes, one observed BGP neighbour, and the IPv6 block 2602:fa20::/40.

Notable

  • Two blocks are netname MISTY-NET and MISTY-NET-1, registered to the proprietorship itself.
  • Two are netname NETBLK-IIC, registered to a datacomm company; one is netname MENDELSON, registered to a computer consultancy.
  • Sampled names read bcast-198-178-250-255.mgtinternet.com and net-198-137-254-64.mgtinternet.com.
  • The name for 198.137.254.127 is bcast-198-137-254-96.mgtinternet.com.

Interesting

  • That last name is the tell. The address ending in 127 is the broadcast address of a /27 whose network number ends in 96, and the label carries the network number rather than the address it is attached to. The zone was generated per subnet, and the generator stamped each subnet's identity onto its final address.
  • Marking network and broadcast addresses in DNS at all is a habit from when a person diagnosing a problem read hostnames rather than subnet masks. It makes the structure of the network legible from the outside.
  • Three different registrants behind one small operator, each with its own naming, is a network assembled from address space that other businesses stopped needing.

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: 448 networks and 1,849 prefixes, as published 2026-10-30. 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.
