More About 123NET
123NET operates as a communications infrastructure provider with a focus on fiber-based networking, carrier services, and data center capabilities for enterprises and institutions that need predictable connectivity, interconnection, and hosting environments. The company’s portfolio is typically positioned for organizations that require business Internet access, point-to-point and multipoint transport, and access to regional data centers for colocation and interconnection with carriers and cloud providers.
In networking, 123NET provides Internet access and Ethernet transport services (enterprise networking), commonly used to connect corporate headquarters, branch offices, and critical facilities such as manufacturing plants, healthcare sites, and public-sector locations. These services are usually delivered over owned or managed fiber infrastructure and rely on standard protocols such as Ethernet, Multiprotocol Label Switching (MPLS) in some designs, and IP routing to integrate with customer Wide Area Network (WAN) architectures. Enterprises often use these circuits as primary or secondary WAN links, integrating them into Software-Defined Wide Area Network (SD-WAN) or hybrid WAN topologies managed by in-house network teams or third-party providers.
The company’s data center and colocation services (data center infrastructure) support customers that want to house servers, storage, and network equipment in third-party facilities rather than on-premises (on-prem). 123NET data centers typically offer power redundancy, cooling, physical security, and cross-connect options to carriers and other service providers present in the facility. Enterprise and carrier customers can use these sites as aggregation hubs for regional connectivity, as Disaster Recovery (DR) locations, or as hosting points for latency-sensitive applications that serve local users.
Voice and unified communications offerings (business voice) from 123NET are generally based on Session Initiation Protocol (SIP) and IP telephony standards, enabling organizations to run business voice, trunking, and possibly hosted voice features over IP networks. These services can integrate with on-prem PBXs, IP-PBX systems, or UC platforms, using SIP trunks for call control and routing. Enterprises deploy these voice services as part of converged voice-and-data networks, often alongside the company’s Internet or private connectivity.
Cloud and network interconnection services (cloud connectivity) allow customers to connect from 123NET’s network or data centers to public cloud platforms and other external service providers through private or high-capacity links. This supports hybrid IT architectures where workloads run in both on-prem or colocated environments and in public clouds, while maintaining predictable bandwidth and latency characteristics compared with general Internet paths.
Within an enterprise IT directory or marketplace taxonomy, 123NET fits into categories such as regional fiber and Internet Service Providers (ISP) (connectivity), carrier and wholesale network services (carrier Ethernet and backhaul), data center and colocation providers (data center infrastructure), and business voice and SIP trunking providers (communications and collaboration). Its offerings are used as building blocks for network underlay, colocation hosting, and telephony services across a range of industries that prioritize deterministic regional connectivity and access to local data center resources.
