Custom domains

If the environment is configured with a custom domain, only one SPN is required. The address varies depending on the DNS result. See the examples below for more information.

Example 1: DNS result from nslookup

c:\>nslookup -type=A sso.example.com
1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa
        primary name server = 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa
        responsible mail addr = (root)
        serial  = 0
        refresh = 28800 (8 hours)
        retry   = 7200 (2 hours)
        expire  = 604800 (7 days)
        default TTL = 86400 (1 day)
Server:  UnKnown
Address:  ::1Non-authoritative answer:

Aliases:  sso.example.com
          45ffcbe6-ec42-48d2-999e-89a7eae22ea9.edge1.pingone.com

Based on this DNS result from nslookup, the SPN address is HTTP/d3laihe2ro8a3z.cloudfront.net. This remains true regardless of the PingOne region.
