Summary
Tavola Conectividade Ltda.
isp telecom business
Its two blocks carry registry counters two orders of magnitude apart, one of them only three digits long.
What it's used for
- A regional ISP's network. 6,144 addresses across two IPv4 prefixes plus a full
2804:3a50::/32of IPv6, with 25 observed BGP neighbours.
Notable
200.142.240.0/20carries the netname33136and200.189.48.0/21carries796, both registered to the same company.- Six addresses were queried for reverse DNS and none returned a name.
- Both IPv4 blocks sit in ranges the regional registry issued to providers in the country.
Interesting
- A three-digit netname means the block was registered while the counter behind it was still low, so this operator has been holding address space since the registry was young. The five-digit netname on the other block is the same company coming back much later. Two numbers, two decades apart, and no words in either.
- Twenty-five neighbours against two announced prefixes is a heavily peered network with very little to announce. Exchanges in this region make that cheap, and the peering count says more about the operator's traffic than the address count does.
- The IPv6 allocation is a provider-sized
/32, announced whole. Nothing about the older protocol's scarcity carried over: this network's IPv6 is a single unbroken block while its IPv4 is two fragments acquired a generation apart.

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: 442 networks and 1,772 prefixes, as published 2026-10-15. 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.
