Customers will see a new route configured on a newly provisioned customer host or on a customer host after a portal-initiated OS reload. This is part of a greater goal to enable new services and offerings for SoftLayer customers. This route will direct traffic addressed to hosts configured out of the 220.127.116.11/16 network block (18.104.22.168 -22.214.171.124) to the back end private gateway IP address configured on customer servers or virtual server instances.
The 126.96.36.199/16 address space is assigned to SoftLayer by IANA and will not be advertised over the front end public network. This space will be used exclusively on SoftLayer’s backend private network, will never conflict with network addresses on the Internet, and should never conflict with address space used by third-party VPN service providers.
This new route is similar to the 10.0.0.0/8 route already located on SoftLayer hosts, in that SoftLayer services are addressed out of both ranges. Also, both the 10.0.0.0/8 route and the 188.8.131.52/16 route will need to be configured on a customer host if it is required to access all SoftLayer services hosted on the back end private network. Unlike the 10.0.0.0/8 range, the 184.108.40.206/16 range will be used exclusively for SoftLayer services. Customers will need to ensure that ACL/firewalls on customer servers, virtual server instances, and gateway appliances are configured to allow connectivity to the 220.127.116.11/16 network block to access these new services.
