Resolving DNS

The BankID Server must be able to resolve the following DNS names depending on the environment:

Internet

DNS	Internet IP address
services-preprod.bankid.no	91.102.24.82
va-preprod1.bankid.no	91.102.24.76
sdm-preprod.bankid.no	91.102.24.84
services.bankid.no	91.102.25.100
va1.bankid.no	91.102.24.134
sdm.bankid.no	91.102.25.50

Table 14 – Internet DNS names and IP addresses

Extranet

DNS	Extranet IP address
sdm-preprod.bankid.no	91.102.24.209
sdm.bankid.no	91.102.25.163
services-preprod.bankid.no	91.102.24.241
services.bankid.no	91.102.25.220
va1.bankid.no	91.102.26.110
va-preprod1.bankid.no	91.102.24.225

Table 15 – Extranet DNS names and IP addresses

Client proxy

Merchants must allow for requests from the Client proxy:

DNS	Internet IP address
https://cp-preprod.bankid.no/clientproxy	91.102.27.1 (public address)
https://cp.bankid.no/clientproxy	91.102.25.68 (public address)

Table 16 – Client proxy DNS names and IP addresses

Also note that if the Web-client detects any of the following error codes when communicating with the Client proxy, the handleError() request from the client will be sent directly to the merchantURL set in the initSession() request:

BID-20C1 - PROXY_COMMUNICATION_ERROR¹
BID-20C4 - PROXY_COMMUNICATION_TIMEOUT
BID-20C5 - PROXY_COMMUNICATION_ABORT

This means that the merchantURL must be accessible for the Web-client even though a Client proxy is in use, see also 3.2.3.
