How do I find my IP address?

The fastest way to find your IP address is to open ipnow.dev — your public IP is shown instantly. No app, sign up or technical knowledge required.

What is the difference between IPv4 and IPv6?

IPv4 is the older 32-bit address format (e.g. 99.33.79.49). IPv6 is the newer 128-bit format that provides many more addresses. Many devices now have both.

How do I SSH into my home computer from outside?

Forward the SSH port (default 22) on your router to the target machine's local IP, then connect with `ssh user@YOUR_PUBLIC_IP`. Use SSH keys and consider changing the port for security.

How do I whitelist my IP for SSH on a cloud server?

In your cloud provider's firewall/security group, add a rule allowing port 22 only from the public IP shown above. This blocks all other IPs from attempting SSH, dramatically reducing attack surface.

What if my IP changes and breaks SSH access?

Use a DDNS hostname so you can connect by name instead of IP. For cloud allowlists, update the firewall rule when your IP changes, or connect through a VPN/bastion host with a stable IP.

Is it safe to expose SSH to the internet?

It is riskier than keeping it private. If you must, use SSH keys (not passwords), disable root login, run fail2ban, and allowlist specific IPs. Safest of all is putting SSH behind a VPN like WireGuard or Tailscale.

What is my IP address for SSH?

Q: What is my IP address?

Your IP address is a unique number that identifies your device on the internet. ipnow detects and displays your public IPv4 and IPv6 address at the top of this page automatically.

Your public IP (shown above) is what you use to SSH into a machine on your network from outside, or to whitelist yourself on a remote server or cloud firewall.

Your public IP address

216.73.216.157

IPv6Not available

This is the address that websites, apps and online services see when you connect. ipnow doesn't store or log it.

Location

Network & ISP

Location is estimated from your IP address and may differ from your exact physical location.

IP addresses and SSH access

How your public IP is used for SSH — both for reaching your own machines and for allowlisting on remote servers.

SSH into your home machine

To SSH into a computer on your home network from outside, you connect to your public IP (shown above) on the SSH port. Your router must forward that port to the target machine's local IP. Then run `ssh user@YOUR_PUBLIC_IP -p PORT` from anywhere.

Whitelisting your IP on remote servers

Cloud providers (AWS, GCP, Azure, DigitalOcean) let you restrict SSH access to specific IPs via security groups or firewall rules. Add the public IP shown above to the allowlist so only your connection can reach port 22 — a major security improvement over allowing all IPs.

Handling a dynamic IP for SSH

If your public IP changes, saved firewall allowlists and connection targets break. Use a DDNS hostname (No-IP, Duck DNS) so you can `ssh user@yourname.ddns.net` regardless of IP changes. For cloud allowlists, update the rule when your IP changes, or use a bastion/VPN.

Securing SSH access

Change the default SSH port (22) to reduce automated scanning, disable password auth in favor of SSH keys, and restrict access by IP where possible. For maximum safety, place SSH behind a VPN (WireGuard/Tailscale) so it is never directly exposed to the internet.

SSH exposure and your IP

The security implications of exposing SSH and how to reduce risk.

What exposing SSH means

Forwarding an SSH port to the internet makes your machine reachable at your public IP. Automated bots constantly scan for open SSH ports and attempt logins. Key-based authentication and IP allowlisting are essential protections.

We never log it

ipnow shows no ads and runs no trackers. We never store or log your IP address on our servers. Geolocation and ISP details are fetched from privacy-respecting third-party providers.

Best practices for secure SSH

Use SSH keys (never passwords), disable root login, install fail2ban to block brute-force attempts, and prefer a VPN or Tailscale so SSH stays off the public internet entirely. Allowlist only the specific public IPs that need access.
