Residential ARIN Cable/DSL/ISP
Summary
SRT Communications
isp telecom infrastructure
Three different reverse naming schemes running side by side in one zone, on a network of only six prefixes.
What it's used for
- A telephone cooperative's broadband network. 41,984 addresses across six IPv4 prefixes plus one IPv6 prefix,
2605:4200::/32, with six observed BGP neighbours.
Notable
- The netnames run
SRTTEL-1throughSRTTEL-5, plusSRTC, all registered toSRT Communications, Inc. - Fifteen of eighteen sampled addresses returned a name, in three forms:
255.159.207.74.srtnet.com,255.111.221.216.static.srtnet.comandstatic-162-247-189-0.srtnet.com.
Interesting
- The first form writes the address backwards with dots; the second does the same but adds a subdomain; the third writes it forwards with dashes and puts the word in front. All three are generated, all three answer, and they exist because each block was turned up by a different generation of tooling.
- Whether an address is called static is expressed two different ways as well: once as a subdomain, once as a prefix on the label. A parser reading these would need to know both.
- Six prefixes and five numbered netnames is a cooperative that acquired space in five separate rounds and filed each the same way. Compared with the sprawl elsewhere in this range, it is orderly.
- Fifteen of eighteen answering is the mark of a provider that names every line as it is provisioned, rather than only the ones in service.

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: 447 networks and 1,848 prefixes, as published 2026-10-31. 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.
