 -----END DH PARAMETERS-----
 
-These are the 4096 bit DH parameters from "Assigned Number for SKIP Protocols"
-(http://www.skip-vpn.org/spec/numbers.html).
-See there for how they were generated.
-Note that g is not a generator, but this is not a problem since p is a safe prime.
+"4096-bit MODP Group" from RFC3526, Section 5.
+
+The prime is: 2^4096 - 2^4032 - 1 + 2^64 * { [2^3966 pi] + 240904 }
+
+RFC3526 specifies a generator of 2.
+
+The generation of the group is described in RFC 2412.
