How to Use IPMusk Proxies in Octo Browser

Which IPMusk proxy to pick

Long-lived accounts: Static ISP, one fixed IP per profile. The IP stays the same every day.
Short tasks: sticky Rotating Residential (1, 3, 10 or 30 minutes on one IP).
Scraping without logins: Rotating Residential. A new IP on every request will break logged-in sessions.
Budget work: Datacenter is cheaper but is not residential or ISP.

Octo Browser installed and signed in. The number of saved proxies depends on your subscription. Temporary proxies are unlimited on every tier.
An IPMusk proxy line.
Residential: dashboard → Residential → Connect (/app/residential/connect). Pick country, session type and protocol, then copy the line.
Static ISP or Datacenter: dashboard → Static ISP → Proxies (/app/isp/proxies) or Datacenter → Proxies (/app/datacenter/proxies). Open a proxy to see its host, port, username and password.
Use HTTP for Static ISP and Datacenter. Residential can use HTTP or SOCKS5.

1
Open the profile
Create a new profile, or edit an existing one, and find the Proxy / VPN field.
2
Set a new proxy
Choose the option to set a new proxy. This creates a temporary proxy tied to that profile.
3
Paste the line
Click the host field ("Enter IP or domain") and paste. Octo reads host:port:username:password, username:password@host:port, and the same with a protocol in front, such as http://PROXY_HOST:PORT:USERNAME:PASSWORD or socks5://USERNAME:PASSWORD@PROXY_HOST:PORT. The fields fill in for you.
4
Check the type
Make sure the protocol is HTTP for Static ISP and Datacenter, and the one you picked on the Connect page for residential.
5
Press Check proxy
A green "Available" message with the country flag means it works.
6
Save and start
Leave "URL for IP Change" empty. Save the profile and press Start.

Octo Browser's help pages do not describe a bulk-import button for proxies, so do not expect a file upload.

1
Save each proxy to the Proxy Manager
When adding a proxy, tick "Save to the Proxy Manager" and give it a clear name, like us-isp-01. After that you pick it from a list, with no retyping.
2
Assign from the list
In each profile, select the saved proxy in the Proxy / VPN field. Keep one Static ISP proxy per profile.
3
Manage in bulk
In the Proxy Manager, select many proxies to check or delete them together. The list shows status, country, IP and time zone.
4
For large batches, use the API
Octo's automation API has a create-proxy call and lets you send a proxy with a profile. Map IPMusk's host, port, username and password to the matching fields, plus a type and a title.

Languages, Timezone, Geolocation: leave the defaults. Octo reads the external IP when the profile starts and sets them to match. Do not set them to "real".
WebRTC: keep "Based on IP" so it shows the proxy IP. "Disable UDP" is a stricter option if you see leaks.
Do not share one Static ISP address across many profiles.

1
Start the profile
Octo checks the connection on launch. Wait for the window to open.
2
Open an IP checker
The IP and country should match your IPMusk proxy.
3
Compare time zone and language
They should fit the same country.
4
Run a WebRTC test
It should show the proxy IP, not your own.

Auth error or 407: copy the username and password again from IPMusk and remove any spaces.
Wrong protocol: a SOCKS5 line pasted as HTTP fails. Match the protocol to what you chose on the IPMusk Connect page. Static ISP and Datacenter use HTTP.
Timeout or "Unavailable": Octo notes the checker can be blocked by your internet provider even when the proxy works. Try a phone hotspot.
Geo mismatch: IP databases differ slightly. Check two or three sites, and confirm the country on the IPMusk Connect page.
IPv6 host: write it in brackets, like [host]:port:username:password.
