isp residential business us

The AS handle PORT-NETWORKS-BALTIMORE is held by Port Networks, Inc.

What it's used for

  • The address space carries residential and business internet services, evidenced by the reverse DNS record rtr.c34887.portnetworks.net and netnames such as PORT-NETWORKS and PORT-NETWORKS-02.
  • The AS announces 5120 IPv4 addresses across 8 prefixes with only 3 observed neighbours, a ratio that indicates an access or eyeball network rather than a transit provider.

Notable

  • All registrants for the announced prefixes are Port Networks, Inc., matching the AS holder name.
  • The address inventory consists of a mix of /21, /22, /23, and /24 blocks, primarily within the 205.215.240.0/21 range and a separate 104.145.220.0/22 block.

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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
