NSLookup is an internet utility to get domain's DNS information. It will help you to find the target IP address of a domain or see what name servers are set on a specific domain. NSLookup for iPhone and iPad allows you to see the public DNS records of domains or sub domains. Then you may also query the NS and CNAME records. It's also possible to force it to get an authoritative response from main DNS server of the domain. This advanced version does not have any advertisement.

Web Toolbox will help you keep an eye on your sites and web servers. With a few simple steps you can set up automated checks on the responses and content of your web pages. You will be able to run them individually or in batches whenever you want directly from your iPhone and iPad without any subscription. You will be able to configure different types of automated checks: - HTTP Status Code: Indicate the expected HTTP status code, if the code obtained is different the check will fail. - HTTP Header: You will be able to indicate the name of an HTTP header whose content you want to check, you will be able to do an exact check or search for a string within the value. - Content: You will be able to search for an HTML element within the page by indicating its CSS selector and check its content. - Custom JavaScript: Finally you will be able to run a JavaScript script within the page and check its result. You will also be able to decide whether to run the checks on the simple textual response of your web page, or to render the page in a real web browser. To help you identify issues on your websites, Web Toolbox includes several tools: - DNS: A DNS client that will allow you to query DNS servers in your local or remote network with the most popular preconfigured ones (Google DNS, OpenDNS, Cloudflare) - GeoIP: This tool will allow you visually to pinpoint the geographic location of any IP address, as well as obtain other information about the address such as the ISP - Whois: A completely revised Whois client to allow you to access domain name information more easily. In addition to the classic text response, for most Whois servers, you will have access to a tabular mode that will make the domain data more readable and usable.
