1) Sometimes it is blocked so that it cannot be used by spammers, hackers and other anti-social elements.
2) Due to bad email practices, increased the flow of spam looking emails from an IP address or misconfigured DNS Settings etc.
3) When you logged in from a public network like from train, bar, or an airport and some other people use it for illegal activities, it will lead your IP address to block.
4) If your computer is effected with Virus and sending out spams then your address can be blocked.

2) Enterprise SPAM firewalls: These are real-time network distributed blacklist that is maintained by spam firewalls. It is used basically by the corporate IT department.
3) Private/ISP Blacklist: Major ISP maintains their blacklist of their own. In some cases, you can ask questions and in other cases, you cannot. For example (outlook.com and Yahoo maintain their own blacklisting data & have their own spam filtering technology) In order to confirm that your IP address is blocked you need to check your monitor server log.
There are 120 public blacklists. Mentioning the name of three where you can check that your IP address is blocked or not.

If in case after following above-mentioned steps still your problem is not resolved you can seek help from Microsoft Smart Network Data Services (SNDS).
