Suddenlink uses reasonable network-management practices to help accomplish the following goals:
- Allow customers to access and use any legal Web content they prefer
- Mitigate network congestion, which can interfere with customers’ preferred online activities
- Promote customer compliance with our Acceptable Use Policy and Residential Services Agreement
- Help prevent customer harm or inconvenience from malicious or illegal traffic.
In pursuing these goals, we are mindful of the dynamic nature of customer Internet habits and related public-policy discussions. Accordingly, while we are confident our network-management practices are reasonable, equitable, minimally intrusive, and consistent with FCC regulations, those practices are not static; they are actively reviewed and refined in order to provide our customers with the best possible Internet experience. To that end, we occasionally conduct short-term tests of new network-management techniques. If such techniques are adopted for regular or extended use, we will include a description of them on this page, along with other applicable updates to the following information about our current, established practices.
- We regularly invest in additional fiber nodes, network equipment and facilities to make available more bandwidth per home and greater downstream and upstream system capacity.
- On residential accounts, we block ports 25, 68, and certain others, to enhance network security and performance. To help prevent parties with malicious intent from compromising or disrupting our network, we do not publish all blocked ports.
- Based on the experience of our engineering team and their monitoring of Arbor alerts, virus alerts, atypical packet swarms, IP addresses and continent codes known or deemed to be abusive, we strive to intercept spam, viruses, denial-of-service attacks, and other malicious or illegal Internet traffic.
- To help prevent disruption to Internet service, we do not support DOCSIS 1.x modems or non-DOCSIS devices, nor do we allow certain other devices (such as routers and modems capable of generating broadcast storms) to connect to our network. In addition, we do not allow devices with cloned MAC addresses to connect to our network because the use of such devices is prohibited by law.
- Residential customers are prohibited from using or running dedicated, stand-alone equipment, servers, or programs for commercial or other non-personal reasons, including but not limited to email, Web hosting, file sharing, and proxy services or servers (e.g. FTP, file, or game servers). For further information regarding prohibited uses, see our Acceptable Use Policy.
- In most of our service areas, we apply bandwidth usage allowances to residential Internet accounts, with incremental bandwidth available for a nominal, incremental fee.
- We prioritize Suddenlink voice packets in order to provide quality service to our phone customers.
- In the cable systems listed and only through the means described in this document, we may limit the bandwidth available to individuals whose usage materially exceeds the typical customer usage in those cable systems.
