As a general matter, you will not need to do anything with these IP addresses as our provisioning servers will take care of SIP device configuration.  Each client's dedicated domain name will resolve to the appropriate server automatically.


In certain situations, however, it may be necessary to open ports in the client site firewall.  We recommend utilizing the subnet ranges, as there may be more than one server on a given Geo-Node that can serve the same function.  The following are Subnet Ranges and IP Addresses that are in use by our system:


70.42.44.0/24 (New Jersey Geo-Node)

75.98.50.0/24 (Dallas Geo-Node)

216.24.144.0/24 (Las Vegas Geo-Node)

199.21.246.224/27 (Minneapolis Geo-Node)

207.254.80.0/24 (Atlanta Geo-Node)

18.209.52.107/32 (Instant FAX ATA System)
