What are GoToConnect's IP blocks?

GoToConnect Voice handsets must have unfiltered access to GoToConnect’s network ranges. These IPv4 and IPv6 ranges are listed below and are also available in a automatically parsable (and updated) form at the bottom of this article.

Description Block Netmask Wildcard
GoToConnect Block 1 199.36.248.0/22 255.255.252.0 0.0.3.255
GoToConnect Block 2 199.87.120.0/22 255.255.252.0 0.0.3.255
GoToConnect Block 3 162.250.60.0/22 255.255.252.0 0.0.3.255
GoToConnect IPv6 2606:CB00::/32

Our recommendation is to create explicit rules that allow traffic to and from GoToConnect’s IP blocks (LAN→ WAN and WAN→ LAN) and set high in priority — even if this is implicitly stated in another access rules down the list. Be sure that the phones are using a reliable DNS server as a DNS failure can delay or prevent call setup. We strongly recommend using Google’s DNS, 8.8.8.8 and 8.8.4.4.
