Unclassified RIPE
Summary
TeleEst
isp business infrastructure
Two adjacent blocks that still cannot be announced as one.
What it's used for
- A regional internet provider. Two IPv4 prefixes announced from Romania, no IPv6, a thousand two hundred addresses, through one observed BGP neighbour.
Notable
- The two blocks sit next to each other in the address space, a
/22followed immediately by a/24, yet they still need two routes. - Both carry the same netname, the company name and nothing else, and the same two registrants.
- Every answering address uses one form: a word for static, the address in dashes, then the company domain.
- Five of six sampled addresses answered, with no variation in the scheme.
- Six addresses were queried for reverse DNS and five returned a name.
Interesting
- Adjacency is not enough to merge two routes. A single announcement has to start on a boundary that matches its own size, and a
/22followed by a/24does not line up, so the extra routing entry is unavoidable rather than careless. - Labelling every address as static tells anyone looking that these are assigned rather than handed out on demand, which changes how mail from them is treated.
- One naming scheme, one netname, two registrants, no exceptions anywhere: a small provider whose records were set up once and left correct.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
