2.1.0 --> 2.1.1 Tank Auth IP addresses?

I am following the above guide to upgrade my CI installation from 2.1.0 to 2.1.1

Step 3 says to UPDATE YOUR IP ADDRESS TABLES
ALTER TABLE ci_sessions CHANGE ip_address ip_address varchar(45) default '0' NOT NULL

Does this mean that I have to run this ALTER SQL command for EVERY SINGLE ip address field that is in the TANK AUTH AUTHENTICATION DB?

IP address fields in tank auth DB:

‘last_ip’ in table ‘users’
varchar(40) utf8_bin Null(No) Default(None)

‘last_ip’ in table ‘user_autologin’
varchar(40) utf8_bin NULL(No) Default(None)

‘ip_address’ in table ‘login_attempts’
varchar(40) utf8_bin NULL(No) Default(None)

‘ip_address’ in table ‘ci_sessions’
varchar(16) utf8_bin NULL(No) Default(0)
