# Connect to different network

In venus, it is easy to decide whether to connect to different networks by setting the startup parameters.

# Mainnet

./venus daemon #connect to mainnet by default

# Calibration Network

parameters must be configured to connect to the calibration network.

./venus daemon --network cali

# Nerpa Network

parameters must be configured to connect to the nerpa network.

./venus daemon --network nerpa

# 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
