Summary

Atlantech Online

United States · AI-generated

isp hosting legacy

ATLANTECH is Atlantech Online, Inc., a business-focused internet and data-centre provider serving the Washington, D.C. metropolitan area from Maryland.

What it's used for

  • Dedicated business internet access, colocation, cloud and hosted-VoIP services for organisations in Maryland, Virginia and the District of Columbia.
  • Backbone and firewall rDNS follows a site-coded scheme on atlantech.net (interfaces named for Silver Spring, Rockville and Philadelphia points of presence), while customer space resolves to the customers' own domains — law firms, agencies and small businesses.

Notable

  • This is a B2B network, not an eyeball ISP: there are no consumer DSL or cable subscriber pools in the space, only business circuits and hosted servers.
  • Registered with ARIN in January 1997, and the org record dates from the same day — an original allocation to a company that still holds it, which is not the norm for numbers in this range.

Interesting

  • Because Atlantech mixes transit customers and its own hosting, a single prefix here can be either a business office's uplink or a rack in its data centre; geolocation to the D.C. metro is safe, but "residential" never is.

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 1,771 prefixes, as published 2026-10-15. 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.
