IPdata API is the best way to get information about any IP address. They have a summary page which gives you overall info. I personally use Raw data section which has good info to find out any CIDR block related to a company. Review collected by and hosted on G2.com.
Bad thing about the API is, it sometimes doesn’t provide any domain info in company info section. Sometimes the info seems to e wrong if the compare the IP data from different platform. Review collected by and hosted on G2.com.
