Class C IP Checker
Find all websites hosted on the same Class C IP range!
What is a Class C IP Address?
A Class C IP address is defined by the first three octets of an IPv4 address (e.g., 192.168.1.x). The Class C range represents the network portion, while the last octet (1-254) identifies individual hosts on that network. On shared hosting, multiple websites share IPs within the same Class C range.
Our Class C IP Checker identifies all websites hosted on the same Class C IP range as your domain. This is crucial for SEO analysis, identifying shared hosting neighbors, detecting link networks, and understanding IP infrastructure.

📚 Frequently Asked Questions
Q: What is Class C IP in SEO?
A: In SEO, Class C IP refers to the network portion of an IP address (first 3 octets). Backlinks from different Class C IPs are valued more than links from the same IP range, as they show natural link diversity.
Q: Why do multiple sites share the same Class C IP?
A: Shared hosting providers host hundreds or thousands of websites on the same servers, all sharing the same Class C IP range (e.g., 192.168.1.1 to 192.168.1.254) to optimize server resources and reduce costs.
Q: Is sharing a Class C IP bad for SEO?
A: Not necessarily. Reputable shared hosting is fine for most sites. Issues arise only if: 1) Neighbors are spammy/malicious, 2) You're building link networks on same IPs, or 3) Server performance is poor due to overcrowding.
Q: How many websites can be on one Class C range?
A: A Class C network supports 254 host addresses (192.168.1.1 to 192.168.1.254). However, hosting providers can assign multiple domains to each IP, so hundreds or thousands of websites may share the same Class C range.
Q: Should I get a dedicated IP for SEO?
A: A dedicated IP offers minimal SEO benefit for most sites. Focus on quality content and natural backlinks. Consider dedicated IPs for: e-commerce sites needing SSL, email reputation, or avoiding bad neighbor penalties.
Q: Is this Class C IP checker free?
A: Yes! Completely free with unlimited checks. Identify all websites on the same Class C IP range, export results to CSV, and analyze your hosting infrastructure.
