I have a requirement where I need to store an IP address in the table on a rails app. The format could be of IPv4 or IPv6. Currently I thought of storing them as 'strings'. But is this a good approach. Could there be a better alternative here that could accomodate both?

The appropriate PostgreSQL data type is clearly inet.

While inet can also represent a subnet, it is also the appropriate type for a single IP address:

The input format for this type is address/y where address is an IPv4 or IPv6 address and y is the number of bits in the netmask. If the /y portion is omitted, the netmask is taken to be 32 for IPv4 or 128 for IPv6, so the value represents just a single host.

string works as well.

# Migration
t.string   :current_sign_in_ip

# Controller
user.current_sign_in_ip = request.remote_ip
