demon.co.uk IP Lookup

demon.co.uk's IP Address Information

demon.co.uk's IP addresses identify the servers that the domain currently resolves to. IPv4 addresses come from A records and IPv6 addresses come from AAAA records. When your browser connects to demon.co.uk, it uses one of these addresses to establish a connection.

If demon.co.uk has multiple IP addresses, it typically means the domain uses load balancing or a CDN (Content Delivery Network) to distribute traffic across multiple servers. This improves performance and provides redundancy. If one server goes down, others continue serving demon.co.uk's content.

The presence of both IPv4 and IPv6 addresses indicates that demon.co.uk supports dual-stack networking, making it accessible to users on both protocol versions. This is a best practice for modern internet services.

What Is an IP Address?

An IP (Internet Protocol) address is a numerical label assigned to every device connected to the internet. IPv4 addresses use 32 bits (e.g., 192.0.2.1) and IPv6 addresses use 128 bits (e.g., 2001:0db8::1). Domain names like demon.co.uk are human-readable names that map to these addresses via DNS.

When you visit demon.co.uk, your browser first performs a DNS lookup to translate the domain name into an IP address. It then establishes a TCP connection to that IP address on port 443 (HTTPS) or port 80 (HTTP) to load the website.

IPv4 vs IPv6

IPv4 supports approximately 4.3 billion unique addresses, which have been fully allocated since 2011. IPv6 was created to solve this exhaustion problem, providing a vastly larger address space of 340 undecillion addresses (3.4 × 10^38).

Check whether demon.co.uk supports IPv6 by looking for AAAA records. If only A records exist, demon.co.uk is IPv4-only and may be unreachable to users on IPv6-only networks. Modern websites should support both protocols for maximum accessibility.

Many CDN and cloud providers automatically provide IPv6 support. If demon.co.uk uses Cloudflare, AWS CloudFront, or similar services, it likely supports IPv6 through the provider's infrastructure even if the origin server is IPv4-only.

Shared vs Dedicated IP Addresses

On shared hosting, multiple domains share the same IP address. The web server uses the HTTP Host header (or TLS SNI extension) to route requests to the correct website. If demon.co.uk shares an IP with other domains, this is standard practice and does not affect performance or security.

Dedicated IP addresses give a single domain its own address. This can be important for certain SSL certificate configurations on legacy systems, email deliverability (dedicated IPs build their own reputation), and regulatory requirements. Check whether demon.co.uk's IP address is shared by performing a reverse DNS lookup.

IP Lookup for demon.co.uk

This IP lookup tool automatically queries DNS for demon.co.uk's A and AAAA records. You can also use command-line tools: "dig demon.co.uk A" and "dig demon.co.uk AAAA" on Linux/macOS, "nslookup demon.co.uk" on Windows, or "ping demon.co.uk" to see the resolved IP address.

IP addresses for demon.co.uk can change over time: especially if the domain uses a CDN, cloud hosting, or dynamic DNS. Always perform a fresh IP lookup rather than relying on cached results when troubleshooting connectivity issues.
