FIFA 17's ProtoSSL verifies the roster certificate by dNSName only, so the
client must reach the roster as winter15.gosredirector.ea.com. Retested on
Windows 2026-08-23: an IP-addressed roster host is refused even though the
certificate carries IP Address:10.10.0.120 as a SAN.
Public DNS points that name at EA's dead 159.153.51.20, so the client has to
resolve it to us. scoped-dns.py pins exactly that one name and forwards every
other query upstream verbatim, so a client pointed at it cannot lose general
resolution -- verified against www.microsoft.com, github.com and
www.msftconnecttest.com.
Paired with a Windows NRPT rule rather than a hosts entry: per-name, auditable
via Get-DnsClientNrptRule, and revertible in one command. A hosts edit on this
machine had previously taken its whole internet down.
