Reverse names pack the address backwards, an extra identifier, the assignment method and the access medium into one label.

What it's used for

  • A regional internet provider. 33,792 addresses across fifteen IPv4 prefixes, the IPv6 block 2606:5100::/32, and two observed BGP neighbours.

Notable

  • Six of eighteen sampled addresses answered, as 254-55-33-162-108-dhcp.wls.metalink.net and similar.
  • Each name is the four octets reversed, then a number that varies per address, then dhcp.
  • The next label is the medium: wls on most, fib on one, and that one sits under a different provider's domain entirely.
  • Netnames are MTLT on three blocks and the full company name on the rest.
  • Registrants append two or three internal roles after semicolons, including one for DNS and one for abuse.

Interesting

  • A label that states the addresses are handed out dynamically, and by what kind of link, is a support tool. An engineer reading a complaint learns whether the customer is on wireless or fibre before opening a ticket, and so does anyone else looking.
  • One address answering under another company's domain, with the fibre label, marks space operated for or inherited from a second brand.
  • Fifteen prefixes with two upstreams is space accumulated from many small allocations rather than split for routing, which is the normal shape of a provider that grew by buying whatever was available.

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 2026-10-22. 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.
