Summary

LigaT Telecom

Portugal · AI-generated

isp residential cable dsl

LIGAT is operated by LigaT Telecom Sociedade Unipessoal LDA.

What it's used for

  • The address space carries residential and business internet access, evidenced by the netname LIGAT-TELECOM and the operator's classification as a Cable/DSL/ISP.
  • The AS announces 1792 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with 5 observed neighbours, a ratio consistent with an access network providing local connectivity rather than transit.
  • Traffic from this AS consists of subscriber eyeballs and local business endpoints in the Malveira region of Portugal, served via cable and DSL infrastructure.

Notable

  • Registrants for the largest prefixes include Invermae Solutions SL for 185.228.160.0/22 and LigaT Telecom Sociedade Unipessoal LDA for 199.16.242.0/23 and 185.142.131.0/24, indicating a mix of owned and potentially leased or managed space.
  • The inventory includes a /22 block registered to a different entity (Invermae Solutions SL) alongside smaller blocks directly registered to LigaT, suggesting a segmented address estate.

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 1,784 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.
