isp telecom hosting

One address is named, in words, after its position at the top of the block.

What it's used for

  • A regional ISP's network. 2,560 addresses across five IPv4 prefixes plus four IPv6 prefixes, with two observed BGP neighbours.

Notable

  • Four blocks carry the netname MONTI-NET-1 and one carries MNN-8.
  • Three of fifteen sampled addresses answered: top-of-the-net-block2.n-connect.net, monti-ppp190.n-connect.net, and a customer's own name under campcourageous.org.
  • The four IPv6 announcements are separate /48s with unrelated labels rather than pieces of one range.

Interesting

  • A hostname spelling out "top of the net block" in words is somebody documenting their address plan in DNS because that is where they would be looking when it mattered. It is the same instinct that produces a comment in a configuration file, and it survives long after the person who wrote it.
  • Another name marks a point-to-point dial-up link by number, a service that has outlived its customers by decades in this zone. The provider's own domain is nothing like its company name, which is the norm for ISPs that renamed themselves and kept the mail working.
  • A summer camp appears as a customer with its own domain in the reverse zone, which is what a business connection looks like when the business is a charity with one site.
  • Four scattered /48s of IPv6 rather than one larger block means each was requested separately, probably one per customer who asked.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
