As mobile business customers roam around the globe, they are increasingly reliant on Internet services to stay in touch with colleagues, customers and suppliers, and demand the same level of performance they have at the home office. Global DNS services need to be as seamless as possible – yet the global DNS roaming infrastructure is extremely complex and fragmented. As customers travel between cities and across national borders, providers must broker 3G and 4G/LTE connections via the Global Roaming Exchange (GRX) which ensures roaming connectivity using a series of private DNS lookups. These connections span across networks with different protocols and configurations, including IPv6, Dual Stack IPv4-IPv6, GRX/IPX DNS, and DNS 64. Maintaining the underlying infrastructure needed to ensure business-grade communications no matter where customers travel is one of the most demanding challenges for Internet service providers (ISPs) and mobile network operators (MNOs).
Infoblox Solutions for Mobile Roaming
Infoblox solutions help ISPs and MNOs maintain roaming connectivity with support for 3G and 4G/LTE networks and integration to the Global Roaming Exchange (GRX). Infoblox DDI solutions support 3G and 4G/LTE variants with IPv6 and DNS 64, while also handling GRX DNS lookups for the .grx custom root in a robust DNS appliance. DNSv6 support and dual stack IPv4-IPv6 operation are standard features.
Purpose-built, Carrier-grade Appliances
The Infoblox purpose-built, carrier-grade appliance family is secure, hardened and enables automated failover for DNS servers. The Infoblox patented Grid technology enables automation of many of the routine administrative functions and simplifies daily operations in a highly complex global mobile roaming environment.
The Infoblox Grid also provides remote centralized management via a single GUI application, providing the ability to manage multiple servers from a single location. . Extensive reporting allows MNOs to troubleshoot more effectively and to view DNS traffic patterns and understand growth across individual servers or entire server populations, to better plan for capacity and upgrades.
