Sorry for the mini-necro bump...
I was searching the net for DNS numbers to receive Pokes, and came across a really handy one if you are patient...
Please note that you must put this number into both the primary, and secondary DNS numbers.
Primary #: 119.234.3.33
Secondary #: 119.234.3.33
I've taken about 50 Pokes off of this, with only one duplicate so far. It gives out Bond's RNGd Pokes, and someone elses non-RNGd pokes, but even these Pokes have really good (still competitive) IV stats. All of them seem legit. PokeCheck all shows the as legit anyways.
The only exceptions are the over-abundance of randomly natured/IVd DW Mamoswine, and Japanese event Cubchoo it gives (about a 1:3 ratio it seems to me).
If you get past the Mamoswine's and Cubchoo's it gives, it's really worth checking out.
it's a little fun too, since the distribution really does seem completely random, with only one duplicate in about 50 tries so far, not counting Mamo and Cubchoo. Check the IVs, Some of them that appear to be duplicates, aren't.
(I have only tried this on my Gen 5 White cart. I have no ideal if it works in Gen 4.)
