Summary
AMA TechTel Communications
isp legacy
The network of AMA Communications, LLC, the competitive carrier trading as AMA TechTel Communications, serving the Texas Panhandle and West Texas from Amarillo. It is registered under the plain handle AS-6620.
What it's used for
- Retail internet service across Amarillo, Lubbock, Abilene, and surrounding communities, over fiber, DSL, and fixed wireless.
- Reverse DNS shows the mix directly: subscriber pools appear under
amaonline.comwith names likeama-dslst.…for DSL andama-wldhcp.…for fixed-wireless DHCP, alongside hosted mail for local business customers.
Notable
- This is an eyeball network. Most addresses on it terminate at homes and small businesses in a fairly small geographic area, so geolocation to the Texas Panhandle is generally sound.
- The AS announces around a hundred small prefixes, the scattered-block pattern typical of a regional carrier that has accumulated address space over decades rather than receiving one large allocation.

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.
