REST API allowing to perform DNS queries over HTTP, and to get reverse PTR records for both IPv4 and IPv6 addresses. It outputs JSON-encoded DNS responses, and supports both Cross-origin resource sharing (CORS) and JSONP.
Get location information about an IP address. Depending on the specific IP address you can determine the country, region, city, longitude and latitude of the address. Our high quality database for geolocation data is being constantly updated as the internet address allocation changes (the database is usually updated at least once per month). This API can also be used to do reverse DNS (PTR) lookups.
Perform DNS (Domain Name Server) through a RESTful API, obtain parsed results in JSON or XML. A domain has a number of records associated with it, a DNS server can be queried to determine the IP address of the primary domain (A record), mail servers (MX records), DNS servers (NS nameservers) and other items such as SPF records (TXT records).
A collection of tools that allows you gather useful information about your customers. We provide IP to Host (PTR) and Host to IP (A, AAAA, CNAME) resolution in DNS, IP/IPv6, AS, Domain WHOIS lookup as well as location information based on IP or host name via GeoIP2 database.
Check the reputation of an IP address or domain against a comprehensive list of blacklists and blocklists (DNSBLs). We currently check 192 DNSBLs and 37 URI DNSBLs. This API can take anywhere from 5 seconds to 20 seconds to run depending on the current response times of the active DNSBLs. Please Note: you should not call this API repeatedly (or concurrently) in short periods of time or you may get blocked for list abuse.

Have you ever wondered how your smartphone or PC identifies the exact place to go when you type in a domain name such as criciree.com? It is not by luck but because all devices that are connected to the internet utilize an underlying domain name system, which has DNS servers at its core. Before we move any further, what is a DNS server, and how does it work.
DNS is basically an intuitive technology that allows users to access websites with much ease. Often referred to as the internet's phonebook, Domain Name System (DNS) maintains and manages a directory of domain names and translates them into Internet Protocol (IP) Addresses. The DNS server contains a database of several public IP addresses and their associated hostnames. When you type the domain name of the website you wish to visit, the DNS server helps to match it to its associated IP address.
Since it is easier to remember a domain or a hostname, users are not required to memorize the IP address, which is usually in numbers. Conversely, network devices and computers don't work well with names when interacting with each other on the internet. It is for this reason that they use IP addresses.
Whenever you connect to the internet, you are assigned a DNS server by your ISP. However, it can be slower, and it may experience some downtime. You can avoid these troubles by switching to a public DNS server from reputable providers.
As technology continues to evolve, the things that can be performed by DNS have become endless. One of the ways that the core functions of DNS can be amplified is through the use of an Application Programming Interface (API). Therefore, a DNS API can be considered to be a set of improved DNS protocols that can be used to effect and perform various functions in the DNS servers.
A Domain boasts several records. As such, a DNS server can be queried to perform various tasks such as determining the IP address of the primary domain (A record), DNS servers (NS nameservers), mail servers (MX records), and a host of other things such as SPF records (TXT records). DNS APIs become vitally crucial when performing DNS queries. They help you to achieve such queries through HTTP requests, which yield results in XML/JSON-encoded objects.
DNS APIs can be used to get location information about an IP address, to automate settings, and change mail server (MX) and Text (TXT) records, as well as delete records.
