One of the most common questions: “How do I get a Static IP?” or “Why did my IP change?”

​
Rotating Mode (Default)

Best for: Web scraping, crawling, bulk data collection. If you do not add a session flag, every request you make will be routed through a fresh IP address. 
Request 1 → IP A
Request 2 → IP B
Request 3 → IP C
No configuration needed. This is the default behavior.

​
Sticky Sessions (“Static” IPs)

Best for: Account management (FB, IG, Amazon), filling forms, checkout bots. To keep the same IP across multiple requests, define a Session ID.
FlagExample
session_[name]user_XXXX,country_US,session_googleaccount1
As long as you use the same session_googleaccount1, we will route you through the same device. 
curl -x "http://user_XXXX,session_myprofile:pass@portal.anyip.io:1080" http://ip-api.com/

​
Why Did My Sticky IP Change?

Read This Before Asking Support“Sticky” is NOT “Permanent.”We use real peer devices (people’s phones and home wifi), not datacenter servers. Real people turn off their phones, lose signal, or drive into tunnels.
  1. If the peer goes offline: We automatically rotate you to a new IP in the same location to keep your connection alive.
  2. Duration: A session typically lasts up to 7 days, but can be shorter.
This is expected behavior, not a bug.

​
How to Manually Rotate a Sticky IP

If your current sticky IP gets blocked or is too slow, you can force a change:

​
Method A: Change the Session Name

Simply rename your session in your code/bot: 
session_profile1   →  session_profile1_v2
Result: Instant new IP. You can rotate your IP programmatically without changing your code by calling a special URL. Where to find it:
  1. Go to Dashboard > Proxies.
  2. Click “Get Proxy Details”.
  3. Look for the “Change IP URL” under the Proxy credentials section.
URL Format: 
https://dashboard.anyip.io/api/proxy_accounts/[proxy_id]/invalidate/[hash]/session/[session_name]
Example: If your session name is twitter3, your rotation link would look like: 
https://dashboard.anyip.io/api/proxy_accounts/abc123/invalidate/xyz789/session/twitter3
How to use it:
  • Click the link in a browser
  • Call it from a script: curl "https://dashboard.anyip.io/api/proxy_accounts/.../session/twitter3"
  • Set it as a “Rotate” button in your bot/tool
ImportantThe rotation link only works if you have a session_[name] flag in your username. The session name in the URL must match exactly.

​
Advanced Session Options

​
Set a Custom Session Duration

By default, sessions last up to 7 days. You can set a shorter duration (1 to 10,080 minutes) with the sesstime_[minutes] flag: 
# Session expires after 10 minutes
curl -x "http://user_XXXX,session_temp,sesstime_10:pass@portal.anyip.io:1080" http://ip-api.com/
After 10 minutes, the session expires and a new IP is assigned automatically.

​
Disable Auto-Replacement When IP Disconnects

By default, if your sticky IP goes offline, we assign you a new one automatically. To disable this always keep the same IP, you can use the flag sessreplace_false: 
curl -x "http://user_XXXX,session_unique1,sessreplace_false:pass@portal.anyip.io:1080" http://ip-api.com/
If the IP disconnects, you’ll receive a peer_not_found error instead of being switched to a new IP.

​
Avoid IP Collision Across Sessions

Managing multiple accounts? Use sessipcollision_strict to ensure no two sessions ever share the same IP: 
curl -x "http://user_XXXX,session_account1,sessipcollision_strict:pass@portal.anyip.io:1080" http://ip-api.com/
curl -x "http://user_XXXX,session_account2,sessipcollision_strict:pass@portal.anyip.io:1080" http://ip-api.com/
Each session is guaranteed a unique IP.

​
Keep the Same ISP/ASN When IP Changes

If an IP disconnects, we try to find a replacement in the same area. To strictly require the same ISP (ASN), you can use the flag sessasn_strict: 
curl -x "http://user_XXXX,session_bank,sessasn_strict:pass@portal.anyip.io:1080" http://ip-api.com/
This increases success rates for sensitive use cases.
