mendeley.com A Record Lookup

//01

What Is mendeley.com's IP Address?

An A (Address) record maps mendeley.com to a 32-bit IPv4 address. When you type mendeley.com into your browser, the first step is a DNS lookup that returns these A records — the IP addresses your browser connects to in order to load the website.

mendeley.com may have one or multiple A records. A single A record means all traffic goes to one server, while multiple A records typically indicate load balancing or CDN usage, distributing visitors across several servers for better performance and reliability.

mendeley.com's A records are the current IPv4 addresses that the domain resolves to. These can change if mendeley.com switches hosting providers, adds a CDN, or updates its server infrastructure.

What Are A Records?

A records are the most fundamental DNS record type. They provide the direct mapping between a human-readable domain name like mendeley.com and the machine-readable IPv4 address that computers use to route network traffic. Without A records, browsers would have no way to find the server hosting mendeley.com's website.

Each A record has a TTL (Time To Live) value that tells DNS resolvers how long to cache the result. A short TTL means changes propagate quickly but generate more DNS queries. A long TTL reduces DNS traffic but means changes take longer to take effect. mendeley.com's A records each carry their own TTL value.

A Records vs AAAA Records

A records hold IPv4 addresses (32-bit, e.g., 192.0.2.1), while AAAA records hold IPv6 addresses (128-bit, e.g., 2001:db8::1). Both serve the same purpose — mapping mendeley.com to an IP address — but for different versions of the Internet Protocol.

IPv4 addresses are limited to about 4.3 billion unique addresses, which have been fully allocated. IPv6 provides a vastly larger address space. Modern domains like mendeley.com ideally support both protocols. Check mendeley.com's IP address page to see if it has IPv6 support.

Multiple A Records and Load Balancing

When an A record lookup for mendeley.com returns multiple addresses, DNS resolvers typically rotate them in round-robin fashion. This distributes traffic across several servers without requiring a dedicated load balancer. CDN providers like Cloudflare, Fastly, and AWS CloudFront use this technique extensively.

If mendeley.com uses a CDN or cloud hosting, its A records may point to different IP addresses depending on the geographic location of the DNS resolver. This is called GeoDNS or anycast routing, and it ensures visitors connect to the nearest server for optimal performance.
