# Connect to different network
In venus, it is easy to decide whether to connect to different networks by setting the startup parameters.
./venus daemon #connect to mainnet by default
# Calibration Network
parameters must be configured to connect to the calibration network.
./venus daemon --network calibrationnet
# 2k Local Network
in addition to the corresponding network parameters, a network boot file (.car) is required to connect the 2k network.
./venus daemon --network 2k --genesisfile *.car
