More About EarthLink
EarthLink operates as an internet and telecommunications service provider focused on delivering connectivity and associated services to residential customers, small and midsize businesses, and institutional users. Its portfolio centers on broadband internet access delivered via partner networks and various wireline and wireless technologies, with service tiers positioned for different bandwidth and usage requirements.
For enterprise and business environments, EarthLink provides dedicated and shared internet access, often combined with networking and managed support options. These services align with common enterprise networking categories such as business broadband, dedicated internet access (DIA), and managed connectivity. Organizations use these offerings to connect branch locations, remote offices, and distributed workforces to core applications, Software-as-a-Service (SaaS) platforms, and public cloud services.
EarthLink solutions rely on standard internet and networking protocols, including IP, Transmission Control Protocol/Internet Protocol (TCP/IP), Domain Name System (DNS), and common routing and access frameworks used across carrier networks. Depending on the service configuration, connectivity may be delivered over fiber, cable, DSL, fixed wireless, or mobile networks, with Customer Premises Equipment (CPE) such as routers, gateways, and Wi‑Fi access points forming the local access layer. These services are compatible with typical enterprise network architectures that integrate VPNs, Software-Defined Wide Area Network (SD-WAN) appliances, firewalls, and identity and access management platforms.
The company also offers security and privacy services that map to categories such as endpoint protection, identity protection, and secure browsing for consumers and small offices. These tools are typically used alongside third-party email, productivity suites, and collaboration platforms. For many customers, EarthLink acts as a single provider for internet access, domain and email hosting, and basic security, simplifying account management and billing for distributed users or multi-location small businesses.
In marketplace taxonomies, EarthLink aligns to service categories including broadband and Internet Service Providers (ISP) services, business connectivity, managed network and communications services, and consumer and SOHO security and privacy tools. Its offerings are typically integrated into broader network stacks managed by internal IT teams or external MSPs, providing the access layer on which organizations run web, cloud, and SaaS workloads.
