Summary
Silica Networks Argentina
transit legacy
Silica Networks Argentina S.A. is the Argentine arm of Silica Networks, a Grupo Datco company that builds and sells long-haul fibre capacity and IP transit across Argentina and Chile.
What it's used for
- Wholesale connectivity: fibre transport, IP transit and capacity sold to other carriers, ISPs and large enterprises rather than to households.
- Reverse DNS on the announced prefixes is uniformly
…static.silicanetworks.com, statically assigned customer address space with no dynamic subscriber pools of the kind an eyeball ISP produces.
Notable
- Silica operates a DWDM long-haul network crossing the Andes between Argentina and Chile, with onward reach toward Brazil and Uruguay, which is what puts it in the carrier's-carrier tier rather than the retail one.
- The company expanded its Argentine footprint by taking over InterNexa's wholesale fibre operation in the country.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
