Summary
Instituto Costarricense de Electricidad y Telecomunicaciones (ICE)
isp mobile government legacy
AS11830 belongs to the Instituto Costarricense de Electricidad (ICE), Costa Rica's state-owned electricity and telecommunications utility. It is the main carrier of ICE's national network, marketed to consumers under the Kölbi brand.
What it's used for
- National eyeball access. RIS observes roughly 1,910 IPv4 prefixes covering about 1.5 million addresses, plus 38 IPv6 prefixes, against only 18 observed neighbours. That combination, a very large address pool with a small peering fan-out, is the signature of an access network serving end users rather than a wholesale carrier selling transit to other ASes.
- The inventory is almost entirely LACNIC space: aggregates such as a
/12and several/14s out of201.192.0.0, alongside181.193.0.0/16and163.178.0.0/16, with IPv6 out of2001:1334::/30and the2800::range. Blocks of that size are held by incumbent operators, not resellers.
Notable
- ICE is unusual in being one legal entity for both the power grid and the telecom network. The same institute runs generation and distribution as runs fixed broadband and the Kölbi mobile business, so the AS sits under what is, formally, a government utility rather than a private carrier.
- No PTRs came back on the addresses sampled here. That is a sample, not a finding, and nothing about the network's role is inferred from it.

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 1,773 prefixes, as published 2026-10-13. 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.
