Why We Need to Know When Your IP Address Changes

Shift4’s Universal Transaction Gateway® (UTG) users must have a permanent IP address assigned to their PC, both for security purposes and so that the POS/PMS can always communicate. If this IP address is changed, and Shift4 is not informed, clients will not be able to connect to DOLLARS ON THE NET and therefore will be unable to process transactions until the IP address is reported to Shift4. It may be helpful to know that most DHCP (Dynamic Host Control Protocol) servers allow you to allocate what is known as a Permanent Lease. For those Network Engineers that would prefer not to set a Static IP Address for whatever reason, this will allow them to have the best of both worlds by having both DHCP and a constant IP for the UTG.
