Okay. So we have an active domain bit.bit (I am not the owner). It has some history:
[pentarh@pentbook src]$ ./namecoind name_history d/bit

}
]
The only two last records are valid, all others expired.
Native namecoind has no methods for suppressing such expired records. So I make a small patch, which is implementing direct name resolution in namecoind
Method: name_resolve
Args: <name>
Example:
[pentarh@pentbook src]$ ./namecoind name_resolve d/bit
[
{
"name" : "d/bit",
"value" : "{\"ip\": \"78.47.86.43\", \"email\": \"gtempns1@san.gs\", \"info\": { \"status\": \"For sale.\" }, \"map\": {\"\": \"78.47.86.43\", \"www\": \"78.47.86.43\"}}",
"txid" : "bb12684745370c4d785a640fdb1d2dfbe1f6a0ef41ff55f5b18b9c1f331ce614",
"address" : "MzMm4F3mRA9hMpa7ABN9nZCZAq3JWd4UWA",
"expires_in" : 11258
},

Actually I dont know what to do with two active records
Is the only last valid, or both (split brain)? Current patch is:

And I'm in the way to resolve in java this mess into i2p network address
