Yes it is a vanitygen address,  You can easily such address starting with 1Fee, assuming your computer allows up to 1,000 Mkeys/s and thus generating such a prefix requires 77k difficulty, less than a second.
Even 1FeexV is possible in a short time, but the difficulty increases if it is more than 8 distinct characters.
there is nothing special about that address and you can generate a similar prefix that has nothing to do with the network or pay extra fees.
