Summary
ETRN.com
hosting business
One block, one answer, and that answer names a cache.
What it's used for
- A company network. A single IPv4
/22announced from the United States, no IPv6, and one observed BGP neighbour.
Notable
- The block is registered under the netname
ETRN-MKC-NET1, with a registrant field holding three entries joined by semicolons: the company plus an abuse desk and a network operations centre. - One of three sampled addresses answered, with
c-dnscache-mkc1.etrn.com. - That name declares the host's function and carries the same three-letter site code that appears in the AS handle and in the netname.
- The AS handle is
ETRN-MKC, so handle, netname and reverse name all agree on the site.
Interesting
- Two role desks sitting in the registrant field is a field-shape problem rather than an ownership one. Abuse and operations contacts belong in their own contact records, and joining them into the organisation field means anything reading that field as a company name gets three of them.
- The reverse name is unusually informative for a single answer. It says what the machine does, which site it lives at, and that there is expected to be more than one of it. That is three facts volunteered where most records in this range volunteer none.
- One upstream and one block, with the same site code repeated in every identifier, reads as a single-location network that has never needed a second.

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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
