Integrated Network Services

MPLS L3VPN & L2 Circuits

An MPLS-based Layer3 Virtual Private Network (L3VPN) enables a client to utilize private and public IPv4 and IPv6 routing domains across the OARnet backbone. An L3VPN allows for a virtual dedicated any-to-any communication network between many remote locations.

Layer2 (L2) circuits are provisioned for clients requiring dedicated point-to-point connectivity and may be used to implement private interconnects between organizations or connecting to remote locations.


The OARnet backbone provides native support for the familiar 32-bit IPv4 addresses and newer 128-bit IPv6 addressing.

Customers with IPv4 connections to OARnet can be upgraded to concurrently provide IPv6 on the same circuits. Internet, Internet2, and Content services are available via IPv6.

Last Mile Access

Client connections to the OARnet backbone are provided through a last mile access service using one or more carrier partners. OARnet has high-speed interconnects with over 15 last mile partners across Ohio to facilitate a cost-effective solution using a wide range of connectivity options. These include dark fiber, dedicated circuits and shared metro-ethernet connectivity. Clients can use multiple carriers to implement fully redundant geodiverse connections to multiple OARnet PoPs. 

Content Delivery

The OARnet Content Delivery Service provides customers with the option to purchase bandwidth to a select group of partner Content providers at a lower cost than commodity Internet. OARnet Content partners provide high capacity fully redundant geo-diverse server clusters installed on the OARnet backbone for the exclusive use of OARnet customers. Customers can view their Content traffic vs Internet in the OARnet Gateway to help project the Content subscription rate.

Optical Transport

OARnet offers a full suite of optical transport options, including managed outside plant dark fiber DWDM-based, wave services and TDM-based circuits. 

OARnet maintains trained staff, advanced characterization and troubleshooting equipment used for designing and maintaining outside plant fiber.

On-Net (IntraOhio)

OARnet’s 100-gigabit Ethernet network includes connectivity across Ohio (On-Net) that provides speed, redundancy and reliability to all who connect. On-Net (IntraOhio) delivers a wide variety of services and many efficient options for those who connect to OARnet.

On-Net is an integral part of the connection to OARnet. On-Net was the foundation of the network created to supply supercomputer services to all the higher education institutions in Ohio.


OARnet's co-location service provides cost-effective, worry-free space, with connections back to your organization via OARnet's high-speed network. Co-location is a flexible, affordable way to expand computing resources without expensive local facility upgrades.

Domain Name Service (DNS)

OARnet's members and community development clients can receive assistance with the domain name registration process. OARnet provides primary, secondary, and recursive IPv4 and IPv6 DNS service to our clients with geographically diverse redundant servers. OARnet also provides assistance with domain name registration, design and troubleshooting.
