Summary
ISLC
isp hosting
Three sampled addresses, three different services, all numbered.
What it's used for
- An internet service provider's network. 256 addresses in a single IPv4 prefix, with two observed BGP neighbours and no IPv6 announced.
Notable
- The sampled addresses answer as
mail4.islc.net,web3.islc.netandts7a127.islc.net. - The whole footprint is
216.49.160.0/24, carrying the netnameISLCand registered to the company. - The AS handle is the same four letters again.
- Three addresses were queried for reverse DNS and all three returned a name.
Interesting
- Sampling three addresses at random and hitting three distinct roles means the block is densely used, which is unusual in this range where most sampled addresses answer with a carrier template or nothing at all. The counters say there are at least four mail hosts and three web hosts behind these names.
- The third name embeds the last part of its own address, a convention from terminal and access server pools where each line needed a predictable name.
- Naming services plainly is the old provider convention and it works: a reader learns the shape of the network from three lookups. It also tells anybody scanning exactly which host to try first.
- Handle, netname and registrant all agree, so nothing here has been renamed or resold.

Peering at a glance
Internet exchanges
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 2026-11-10, 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: 454 networks and 1,847 prefixes, as published 2026-11-11. 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.
