Summary

Metronet

United States of America · AI-generated

fiber residential isp joint-venture

ELECTRONET is the AS handle for Metronet, a fiber-to-the-home internet service provider.

What it's used for

  • The space carries residential fiber internet traffic, as indicated by the netname HAR-INSTR-BLK22 and the registrant Metronet.
  • The AS announces 8192 IPv4 addresses across 4 prefixes with only 1 observed neighbour, a ratio characteristic of an access network rather than a transit provider.

Notable

  • All four announced prefixes are registered to Metronet, which aligns with the AS holder ELECTRONET - Metronet.
  • Metronet is a joint venture between T-Mobile and KKR, operating as a high-speed fiber internet service provider in the United States.
  • The address inventory consists of four contiguous IPv4 blocks within the 216.173.160.0/22 range, with no IPv6 prefixes announced.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
