Salesforce: Add all Possible IP to trusted Network

Salesforce: Add all Possible IP to trusted Network

Isn't it annoying that we always have to put verification code to login into salesforce whenever we login from different system and we have to provide security code in Eclipse
But its not always possible that we have email access at that time, Specially in the case of shared credentials.

Simplest solution is If we know the IP Range then add your known trusted network IP ranges and then carry on

But in case of public network we don't get static IP so we can't specify IP. Then next thing is can we specify all IP address to our known trusted network IP ranges ????

 Answer is Yes, we can. I would probably advise against it in a production org but it is useful for a developer edition org.

Its difficult to add IP ranges manually and very time consuming.

I could find a package to add all IP:-http://raydehler.com/cloud/clod/enable-all-trusted-ip-ranges-for-a-salesforce-org.html
