IP Address Ranges

As a general rule, you will not need to do anything with these IP addresses, because the provisioning servers will take care of SIP Device configuration. We will provide you with domain names that will resolve to these servers as necessary.
 
In certain situations, however, it may be necessary to allow these ports in your customer's firewall. We recommend utilizing the subnet ranges, as there may be more than one server on one Geo Node that can serve the same function. The following are subnet ranges and IP addresses that are in use by our systems:
 
    70.42.44.0/24- New Jersey
    75.98.50.0/24- Dallas
    216.24.144.0/24- Las Vegas
    199.21.246.224/27- Minneapolis
    50.112.101.114,54.245.113.67,52.32.130.83, 75.101.128.37- Instant Fax Servers
 
New IPs for failover
 
    70.42.69.0/24- New Jersey
    66.150.215.0/24- Dallas
    209.170.195.0/24- Las Vegas
