Summary
Tularosa Communications
isp enterprise legacy
TULAROSA-COMMUNICATIONS is Tularosa Communications, Inc., an independent telephone company and broadband ISP serving the Tularosa Basin of south-central New Mexico. Its network carries residential and small-business subscribers in and around Tularosa, Alamogordo and the surrounding Otero County communities.
What it's used for
RIS currently sees five IPv4 prefixes totalling 78,080 addresses plus one IPv6 /32 (2607:f068::/32), against ten observed neighbours. Ten neighbours for roughly 78k addresses is an eyeball network, not a carrier: an operator that sells transit ends up peering with hundreds of ASes, whereas a rural telco buys a couple of upstreams and hands the rest of the addresses to subscribers.
The reverse DNS settles the point. Sampled addresses across the 67.211, 66.18 and 72.0 blocks come back as hs-88-5.cust.tularosa.net, hs-40-5.cust.tularosa.net and hs-168-5.ala.tularosa.net — "hs" for high-speed, "cust" for customer, plus a router loopback (rtr-lo-generic-160-5.tularosa.net). Those are subscriber access pools with the operator's own naming scheme on them, which is what distinguishes a real access ISP from a network merely holding address space.
Notable
The largest prefix on the AS, 146.5.0.0/16, is not registered to Tularosa at all: ARIN shows it as NSO-SUNSPOT, the National Solar Observatory. The 192.41.211.0/24 seen alongside it belongs to Apache Point Observatory. Both sit in the Sacramento Mountains above Tularosa, and this small telco is the network that carries them to the rest of the internet. It is a good example of why the registrant list has to be read rather than pattern-matched: third-party registrants here are neighbours on a mountain, not leased proxy space.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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 1,783 prefixes, as published 2026-10-17. 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.
