Understanding IP Structures of Websites and Blogs

When users access a blog or website, they usually type in a domain name. However, behind that domain is a numeric address called an IP address, which actually identifies the server. The reason we can use domain names is because of the DNS system. Depending on whether you run a blog or a website, the IP structure used can vary, and understanding this is critical for SEO, security, and traffic management.

 

 

In this post, we'll explain the IP structure of websites and blogs in detail and provide insights into their differences and operational strategies.

1. What is an IP address?

An IP (Internet Protocol) address is a unique numeric address used to identify devices on the internet. While domain names are easier for humans to remember, all communication at the network level occurs through IP addresses.

  • IPv4: Format like 192.168.1.1 (32-bit)
  • IPv6: Format like 2001:0db8:85a3:0000:0000:8a2e:0370:7334 (128-bit)

The server hosting a website or blog also has an IP address. When a user types in a domain, the DNS translates it into the corresponding IP address to enable access.

2. How do websites and blogs differ?

Websites and blogs both deliver web content, but their IP management and operational structures differ significantly.

2.1 Standalone Websites

  • Operated by individuals or businesses via dedicated or leased servers
  • Use fixed IPs or one-to-one mapped dedicated IPs
  • Full control over files and server configuration

2.2 Platform-Based Blogs (e.g., Blogger, Tistory, Naver)

  • Use subdomains provided by the platform
  • Many blogs share a common IP or set of IPs
  • Server, security, and backup are managed by the platform

 

 

3. Comparison of IP Structures

Category Website Blog
IP Type Dedicated (Fixed IP) Shared IP
Domain Custom domain with DNS configuration Subdomain provided by platform
Access Flow Custom domain → DNS → Fixed IP → Server Subdomain → DNS → Shared IP → Platform routing

4. Fixed IP vs Shared IP

Fixed IPs are permanently assigned to a specific server, providing advantages in SSL certificate application, port forwarding, and authentication. In contrast, shared IPs are used by multiple sites and may be cheaper but can have drawbacks in search engine indexing, SSL, and traffic stability.

 

 

5. Why do website operators prefer fixed IPs?

  • Enables individual SSL certificate installation
  • Ideal for cloud services and API servers
  • Search engines evaluate the site independently
  • Firewall and advanced networking configurations possible

6. Can blog users manage IP settings?

No. Blogs run on shared platforms, so users cannot manage IPs directly. However, by connecting a custom domain, you can give your blog a more professional identity and benefit from enhanced SEO.

For example, a Blogger blog can be connected to a domain like myblog.com instead of using blogspot.com, making it more trustworthy in the eyes of search engines.

 

 

7. Conclusion: Choosing Between Website and Blog Hosting

  • If you need full control and server-level configuration: Operate a website with a fixed IP
  • If your focus is content creation and ease of use: Use a platform-based blog

An IP structure isn't just a technical element — it impacts credibility, performance, and even how search engines view your content. Whether you choose a website or a blog, choose based on your goals and how much control you need over the network.

Understanding IP architecture is essential for effective digital strategy.

Why Is the Giraffe's Neck So Long? – Evolutionary Secrets and Survival Strategy

Image
A giraffe strolling across the savannah stands out from afar. Not just because it’s big, but because of its strikingly long neck . So why did giraffes evolve such long necks? Is it simply to reach tall leaves? Today, let’s explore the evolutionary tale behind the giraffe’s neck and how it became a powerful tool for survival.     A Long Neck for High Leaves? That’s Not the Whole Story Most people assume giraffes evolved long necks to reach tall acacia leaves . While that’s partially true, recent research suggests other key factors also influenced this evolution. Acacia trees often bear leaves at heights unreachable by other herbivores, giving giraffes a competitive edge. So yes, feeding competition likely contributed to neck elongation . But the Real Key May Be ‘Fighting’ Behavioral ecology studies since the early 2000s reveal that male giraffes fight using their necks . This behavior, known as "necking," involves swinging their neck...
