AS14945 FMC-401NEWING-LOH - FAIRFIELD MEDICAL CENTER
Unclassified ARIN
Summary
Fairfield Medical Center
enterprise business infrastructure
The AS handle contains a street address.
What it's used for
- A hospital's network. 512 addresses across two IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.
Notable
- The AS handle is
FMC-401NEWING-LOH: the hospital's initials, a building number, a street name cut short, and a location code. 199.103.118.0/24carries the netnameFAIRFIELDMEDICALCENTER, twenty-two characters with no separators at all.98.100.80.0/24carries the generated netnameNET-98-100-80-0-1.- Three addresses answer as
syn-098-100-080-064.biz.spectrum.com, with each part of the address padded to three digits.
Interesting
- Putting a postal address in an AS handle is the most literal identification in this range. It was written by somebody thinking about which building the circuit terminates in, which is the right question for a hospital with more than one site and the wrong field to answer it in.
- The two netnames are opposite failures. One runs the whole name together with nothing to separate the words; the other has no name at all, only the addresses restated. Neither was written by someone expecting a person to read it.
- Zero-padding every part of the address in a hostname makes the names sort correctly as text, which is why carriers do it. It also makes the address slightly harder to recognise at a glance.
- Those padded names belong to a carrier's business service, so this block follows the contract rather than the hospital, and the reverse zone is not the hospital's to change.

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 2026-11-01, 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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
