Frequently asked questions about Cox Business Internet.


Is my Cox Business Internet speed guaranteed?

Cox Business prides itself on delivering quality service and closely monitors our network to ensure maximum performance. However, the consistent delivery of speed varies based on many factors, including customer specific equipment configurations, potential network congestion during peak loads and Internet activity beyond the Cox network. Therefore, actual customer speeds may vary and cannot be guaranteed.

What is the average installation time for Cox Business Internet?

  • If your business is "on net" (buildings and suites already served by Cox Business Services), installation time is typically 5 - 10 working days.
  • If your business is not yet "on net," your sales representative will be able to determine costs and time frames.

What is the process to upgrade my speed?

It's very easy. Simply call your local Cox Business sales or customer care representative. Often upgrades can be handled over the telephone and can be completed in 48 hours or less.

Is my connection shared?

All connections to the Internet are shared at some point. There is no such thing as a “dedicated” connection, as claimed by some providers. Since all connections are shared, providing a high-speed Internet experience depends on your ISP’s network capacity, scalability, and overall architecture. Cox’s local HFC network is interconnected via a high-speed ATM backbone, while our national backbone is composed of fully redundant OC-48 connections with multiple peering points. Both networks are designed to be highly scalable, providing increased network capabilities as demand increases.

What is a static IP and why would I want one?

A Static IP is a numeric, fixed Internet Protocol address on the Internet. It does not change when you log onto your Cox Business account. A Static IP makes it easier for you to be found on the Internet should you want to host an email, FTP or web server, or any other application requiring a static Internet address. Additionally, Static IP’s may be needed for some virtual private networking.

How do I get more e-mail accounts or a larger e-mail box?

Additional accounts are available by simply calling your local Cox Business Services customer care representative. If more storage space is required, Cox offers expanded storage options as well.

How does Cox Business Internet service differ from Cox’s residential high-speed Internet service?  

Cox Business Internet is designed to meet the needs of businesses by offering several service tiers along with business-class service levels, customer support, professional installation and 24/7 technical support. Cox Business Internet also provides business service features such as Online Backup, Security Suite, server hosting, static IPs, additional email boxes, vanity domains, and mass mailing options.  In addition, Cox Business Internet service is designed to support higher traffic levels generated by businesses with multiple users and applications..

Are there any restrictions on how my Cox Business Internet service can be used?

With access to the Internet, each user benefits by being able to share resources and communicate with millions of individuals and businesses worldwide. As with any community, the benefits and services available from Cox Business Internet, and the Internet in general, must be balanced so that other users can also have a productive experience. Please review the Acceptable Use Policy for additional details on the acceptable and unacceptable uses of Cox Business Internet service. Cox Business Acceptable Use Policy.

Do all service providers deliver the same high-performance Internet access?

Not all providers invest in an infrastructure to ensure a high-performance connection. Cox provides a high-speed, redundant, national IP backbone for business customers to use while connecting to the Internet. Further, Cox’s HFC local cable networks have been largely rebuilt in recent years and are designed with growth in mind. The network is highly scalable, enabling expansion of available bandwidth to meet increasing business demands without major network upgrades.

How does Cox's technology differ from the technology that my local telephone company uses to offer DSL service? Can Cox's technology also provide the reliability I need for business Internet access?

DSL technology is delivered over copper, twisted-pair wiring used for telephone service that was installed decades ago for low-speed, low-capacity voice communications; in contrast Cox’s state-of-the-art broadband network was designed to deliver powerful, two-way interactive services. By meeting the stringent standards of Data Over Cable Service Interface (DOCSIS), Cox’s HFC specifications provide user data privacy across the cable network by encrypting and authenticating data traffic flow to and from the cable modem and Cox’s HFC network. Cox’s cable modem services are highly reliable because the architecture provides multiple paths to each of Cox’s nodes serving 1,000 or fewer customers. As such, the self-healing distribution offers the customer a continuous, secure connection to the Internet.

Is the speed of service comparable between hybrid fiber coax (HFC) cable and DSL Internet access?

Cox Business Internet (HFC cable) is consistently fast no matter where your business is located, whereas DSL service typically gets slower the farther your business is located from the telephone company’s central office. Accordingly, even if the local DSL provider advertises high speeds, these speeds may not be available in your area. Even if you are located in the heart of a DSL service area, it’s unlikely that your local DSL provider can offer the same peak download speed performance available from Cox. . To date, Cox’s 50.0 Mbps of download and up to 5.0 Mbps upstream speeds, provide business customers with the fastest, most widely available business-grade broadband service in the marketplace.

Is it true that only DSL Internet access provides a dedicated connection?

Both DSL and cables’ hybrid fiber coax (HFC) technologies provide shared access to the Internet at some point — but in very different ways. In fact, the Internet itself is a network of networks, shared by millions of users worldwide. The only dedicated portion of a DSL circuit exists between the user’s business and the telephone company’s central office. Beyond that point, DSL subscribers are on the telephone company’s metropolitan network, shared with other DSL, data and telephone subscribers. The business user’s connection then is routed to an Internet Service Provider (ISP), where it is shared with all other ISP subscribers before being transmitted to the Internet.

Aren’t all Internet access providers the same?

Cox Business has been delivering reliable telecommunications services since 1993 — well before the quick entry and fallout of many telecom providers and partnerships. Cox Business Services is a division of Cox Communications, a Fortune 500 company and the nation’s 3rd largest cable broadband communications company. Cox has the advantage of being one of the few facilities-based providers in the marketplace. Cox owns and manages its network, which makes a crucial difference in the way it delivers Internet service to business customers. Cox can upgrade its network easily, making sure that its business customers are benefiting from the latest technological innovations. Cox also monitors its network usage to control service delivery and maintain direct accountability to our business customers — providing local customer support and 24/7 business-grade technical support. With Cox, you have one provider for phone, Internet, and video  services , not two or three companies operating under a co-marketing arrangement. This means you enjoy the convenience of one bill, one company and one number to call for assistance.

What is a CIDR Block of IP’s?

CIDR (Classless Inter-Domain Routing) is an addressing scheme for the Internet which allows for more efficient allocation of IP addresses. Using CIDR blocks Cox Business Services can efficiently assign a customer multiple IP’s that are allocated only to them. This block would remain with the Cox Business Internet customer as long as they remain a Cox Business Services Internet customer.

Why would my business require more than 8 IP addresses?

This feature is not recommended for the majority of small businesses as most will not have a need for more than 8 IP addresses. This feature is more suited for medium or larger business that have a specific need for a large number of routable IP addresses. An example is a hotel that may need to assign designated IP addresses to many devices so they can remotely manage them over the Internet.

Why are 3 IP addresses in a CIDR block not usable for end station device addressing?

The first address in the IP assignment is the subnet address. It is used for routing tables only, and is NOT ASSIGNABLE to a device on your network. The second address in the IP assignment is assigned to your router interface. This address is the default gateway that instructs how your internal LAN needs to route traffic to the Internet. The last address in the IP assignment is the broadcast address for the subnet. It is NOT ASSIGNABLE to a device on your network. The remaining addresses are user-assignable. They can be used for devices on your network.

Is a router required for more than 8 IP’s?

Yes. The router must be provided by the customer. Note: The router needs to be a true router that has the ability to establish static routes. Most low end devices sold as routers (e.g. wireless gateways/routers) at consumer electronic stores are actually NAT gateways rather than true routers that can support routing protocols.

Does Cox Business Services sell more than 64 IP’s?

Contact your local Cox Business representative to inquire about your specific need. These requests are handled on a case by case basis.
