DNS Spoofing

DNS Spoofing maps a hostname to an IP address you choose. Use it to try a new server before its DNS record changes, to test a specific edge node, or to point an app at a machine on your network without touching the app's configuration.

How it works on each platform#

• iPhone and iPad. WireLens answers DNS queries inside its local VPN, so a matching hostname resolves to your address for every app on the device while capture runs.
• Mac. WireLens substitutes the address it dials for matching captured hosts. It does not change your Mac's system DNS, so apps that do not go through WireLens are unaffected.

Create a rule#

Open Tools ▸ DNS Spoof and add a hostname and an IPv4 address. The first enabled rule whose host matches wins. A blank pattern and a bare * never match, so a half-filled rule cannot redirect everything.

Tips#

• For HTTPS, the certificate still has to match the hostname. If your test server's certificate is for a different name, the app will refuse it unless the host is decrypted by WireLens, which presents its own certificate for the original hostname.
• To send traffic to a different hostname instead of an address, use Map Remote.

Free and Pro#

The free plan includes one DNS Spoof rule. Pro removes the limit. The MCP tool is add_dns_spoof.
