Persistent IP FAQs for Viasat Business Internet customers



FAQs about persistent IP addresses for Viasat Business Internet customers

As a business customer, you likely need Internet Protocol (IP) addresses that don’t change, so you can monitor your network devices and/or configure firewall rules to protect your networks. Traditionally, Static IP addresses were the only way to provide this capability. Today our Viasat Business Internet service meets this need by providing you with 3 persistent IP addresses at no additional cost. In many ways, persistent IP addresses are easier to manage than manually entered static IP addresses. Once assigned, persistent IP addresses are consistent, publicly available and easy to use.


Common questions about using your persistent IP addresses

How do I set up my equipment to use persistent IP addresses?

Persistent IP addresses are assigned dynamically over the network. On your device, verify that each unique WAN interface is set to DHCP. If the WAN interface is not set to DCHP, update the config and reboot the device. IP addresses will be assigned right away and you will have access to the internet. After the device is connected to our network for 24 hours, the address will remain persistent.

How many persistent IP addresses do I get?
Each Viasat Business Internet account is provided up to 3 persistent IP addresses for free. There is no charge for persistent IP addresses.

Will my IP address change if I reboot my device?

No. Once assigned, persistent IP addresses will remain assigned to the MAC address on your device. New devices must be connected and powered on for 24 hours. IP addresses on devices that have been disconnected or powered off for more than 14 days will be released.

How do I find out what persistent IP addresses were assigned to my equipment?

Once assigned, there are two ways to determine the persistent IP address(es) assigned to your device(s). If you have access to your device's management portal, go to the WAN interface option and you will see the IP address assigned. If you do not have access to your device, our Business Care team can see the persistent IP address that has been assigned.

Do I need any specific configuration on my device (router, switch, firewall, etc.) to get a persistent IP address?

Each unique WAN interface on your device must be configured as a DHCP client. Standard DHCP leases will be renewed to keep the IP addresses active.

I’m using Viasat Business Internet only as a backup or secondary connection. Will the persistent IP addresses stay attached?

Once assigned, persistent IP addresses remain active as long as the equipment is powered on and connected. If the device is disconnected or powered down for over 14 days, then the persistent IP address will be released. As long as the device is connected and powered on, the persistent IP addresses will not change.

What if I want to change the IP address for my device?

If you need to change the IP address assigned to your computer or device, please contact Business Care.

The differences between persistent, static, and dynamic IP addresses


What is an IP address?

An IP address is a unique string of numbers that identifies each computer or electronic device using the Internet. Similar to how someone needs your unique mailing address to send you a letter, each computer or device is assigned a unique identifier (an IP address) to send and receive data over both public and private networks. 

Dynamic IP addresses

A dynamic IP address is a temporary address assigned to a computer or device when it connects to a network. When you connect to a network, your Internet Service Provider assigns a temporary IP address from a pool of available addresses to your device. The next time you connect to a network, a different IP address may be assigned to you from the available pool. For most users, these changes in IP addresses occur silently and are not noticeable. Most ISPs (Internet Service Providers) offer dynamic IP addresses because it’s efficient. However, they can be undesirable for businesses that require remote access, firewalls, and other unique business operations.

Static IP addresses

A static IP address is a permanent address configured to a computer or device before it connects to a network. When you order service with a static IP, an ISP sends you a permanent IP address, mask, and gateway IP for each device that needs to be manually entered on your local device. Once entered, the assigned IP address does not change. ISPs typically charge for static IP addresses.

Persistent IP addresses 
A persistent IP address is similar to a static IP address in that it is uniquely assigned to each device, is publicly addressable, and once assigned to a device, doesn't change. Persistent IP addresses can be used for network management, POS systems, IoT, and VPN connections. Persistent IP addresses are assigned dynamically over the network, making for a more plug-and-play approach instead of manually entering the IP address, mask, and gateway. And best of all, persistent IP addresses from Viasat are free - we offer 3 free persistent IP addresses for each account.
How persistent are persistent IP addresses?
After a device is assigned a persistent IP address, a DHCP renewal occurs within the first hour to ensure that device is meant to be long term. At midnight all active leases are recorded and turned into persistent IP addresses. With persistent IP addresses, equipment can be powered on/off without concern of being assigned a different IP address. If a device is powered off and/or unavailable for more than 14 days, the IP address will be released, allowing other devices to receive one of the three IP addresses.
