Enforcement of Subnet Validation on Order Entry Switches in the Equinix Co-Lo 2.0 Facility
In its network usage guidelines (Network Access Guide, Chapter 12.1.2), Deutsche Börse forbids the usage of the same source IP addresses on multiple lines and participants must only use the subnets assigned to the respective line.
To ensure compliance with these guidelines, Deutsche Börse will switch from passive monitoring to a subnet validation on the switch and activate it on its order entry switches in the Equinix Co-Lo 2.0 facility as follows:
25.01.2025 Side A - XETRA
15.02.2025 Side B - XETRA
Following the activation of subnet validation, participants must ensure that their correct IP address is used when sending messages to the Exchange. Failure to do so will result in the rejection of messages.
