Lookups and conversions return output in seconds. Handy when you are on a call and someone asks for a subnet range or DNS record.
Phone, tablet, or laptop. The layout adapts so you run a DNS check from the server room or your couch.
Every IP tool on this page costs nothing. No trial timers, no export limits on basic lookups.
Network questions tend to fall into a few buckets. Match yours to the right utility and you skip the guesswork.
Someone changed DNS and the site is down. Start with our DNS Lookup tool to confirm A, AAAA, MX, and TXT records match what you expect. Cross-check nameservers with Nameserver Lookup if delegation looks off.
You need the IP behind a hostname. Use Website to IP for a quick resolve, or Hostname to IP when you already have the FQDN in a log file.
You are carving up address space. The CIDR Calculator returns network address, broadcast, host range, and mask from a single notation like 10.0.0.0/22.
You are studying or debugging binary subnets. Pair IP to Binary with Binary to IP to verify hand calculations against a known address.
You want your own public address.What Is My IP shows the IPv4 or IPv6 your connection presents to the internet, useful before whitelisting or testing VPN split tunneling.
Pro tip
Bookmark this page and the two or three tools you reach for weekly. During outages, fewer clicks matter.
Straight answers for sysadmins, developers, and anyone fixing network issues.
Yes. Every tool listed on this page is free with no account required. You open the page, enter your input, and read the output.
No. All utilities run in your web browser. They work on Windows, macOS, Linux, iOS, and Android without plugins.
DNS Lookup returns live DNS records (A, MX, TXT, and others) for a hostname. Domain Lookup focuses on registration data such as registrar, creation date, and contact fields when available from WHOIS.
It reports the public IP address your current connection uses. If you are behind a corporate proxy or VPN, the result reflects that exit point, not your local LAN address.
The CIDR Calculator on Toolexe is built for IPv4 subnets. For IPv6 planning you need a dedicated IPv6 subnet tool or your router documentation.
