Summary
TDKOM Informática Ltda
isp telecom business
Its one reverse name joins the last two parts of the address with a hyphen and leaves the rest as dots.
What it's used for
- A regional ISP's network. 6,144 addresses across two IPv4 prefixes plus a full
2804:7b0c::/32of IPv6, with 30 observed BGP neighbours.
Notable
200.152.64.0/20carries the netname23389and200.192.240.0/21carries2394, both bare numbers, both registered to the same company.- The registrant name is spelled with an accent that the AS handle drops.
- One of six sampled addresses returned a name:
200.152.68-0.tdkom.net.br.
Interesting
- That hostname is half converted. Somebody wrote a template that replaces the last dot with a hyphen and left the earlier ones alone, so the name is neither the dotted address nor the usual all-hyphens form. It works, and nobody has had a reason to look at it since.
- The two netnames are database keys from the registry rather than descriptions, and they are different lengths, so the blocks were issued years apart under a counter that kept running.
- Thirty neighbours against two IPv4 prefixes is the profile of a network that peers widely and announces little. In this region that means an operator sitting on a public exchange, where peering is cheap and transit is not.
- A
/32of IPv6 is the standard allocation for a provider, so this operator holds far more address space in the newer protocol than it will ever need in the older one.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
