About Internet Systems Corporation
Internet Systems Corporation, doing business as Dnsco, is a self-certified small disadvantaged business based in Newmarket, New Hampshire, that sells BIND (Berkeley Internet Name Domain) software subscriptions, maintenance, and support services to federal agencies as a prime contractor operating entirely in the full-and-open competitive space — no set-aside awards in its portfolio. Dnsco is a for-profit child entity of Internet Systems Consortium, Inc., a non-profit organization that develops and maintains BIND, the open-source DNS software underlying Dnsco's federal offerings.
Dnsco's federal footprint consists exclusively of BIND software subscription renewals and maintenance contracts. The vendor has held recurring annual awards from the Social Security Administration since at least 2021, with five visible SSA purchase orders ranging from $48,000 to $52,000 for BIND subscription renewals supporting the agency's Client Server Infrastructure (CSI) environment in its SOHE system and newly added Amazon Web Services cloud infrastructure. In parallel, Dnsco has secured recurring BIND Silver subscription renewals from the Defense Information Systems Agency, with a $225,000 purchase order awarded in September 2022 and a $247,500 renewal awarded in September 2025 (completion September 2028). A single $56,000 contract was placed by the Defense Media Activity. The work is straightforward software-as-a-service renewal: maintenance, support, and license subscription for critical DNS infrastructure supporting federal domain name and IP address translation across agency networks.
Customer concentration is tightly split between DISA and SSA. DISA anchors 65% of combined potential value across five awards ($1.1 million), while SSA accounts for 29% across ten awards ($492,000), and Defense Media Activity rounds out the 16-award portfolio with the remaining 3%. Activity has remained modest and flat — one to two awards per year over the past five years, with a combined potential value of $1.7 million across all sixteen awards in the source data. Only one award ($52,000 to SSA) reaches completion within the next twenty-four months, presenting limited recompete exposure in that window. Dnsco operates as a pure prime (100% of awards); the source carries no subcontract relationships. The vendor's NAICS split runs across Software Publishers (6 awards), Other Computer Related Services (6 awards), and Custom Computer Programming Services (1 award), with PSC codes mirroring software maintenance and licensing services.
