It is unlikely. It is easier for hackers to attack with the help of malware than to "break" directly to you through an IP address. An unsecured IP address by itself doesn't give them any important information other than what city you're in. However, you should not give up vigilance. Even this knowledge alone can be used by attackers in hybrid attacks that are not limited to your computer and network. In addition, knowledge of this address can serve hackers in complex, multi-channel attacks, where malware and any equipment go alongside social engineering techniques.
