dsl business isp consulting

PARALLAXSYSTEMS is the AS handle for Parallax Systems, a Washington DC-based IT consulting firm that also operates a DSL internet service.

What it's used for

  • The address space carries DSL access traffic, evidenced by reverse DNS entries such as 102-254.dsl.parallax.ws and du-border.richmond.parallax.ws.
  • The network announces 3328 IPv4 addresses across 3 prefixes with only 3 observed neighbours, a ratio indicative of an access or eyeball network rather than a transit provider.

Notable

  • Registrants for the two largest prefixes are RICHMONDS FEED SERVICE INC (netnames RICHMOND654-104 and RICHMOND75-100), while the smallest prefix is registered to Ray Ontko & Co. (netname RAYONTKOCO), suggesting leased or historically allocated space rather than direct corporate ownership of all blocks.
  • The inventory consists of three distinct IPv4 prefixes: 12.161.104.0/21, 12.176.100.0/22, and 199.164.165.0/24, with no IPv6 prefixes in the inventory.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
