About this network

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.
