Proxy IP blocked solution | IP blocked quick replacement solution

What are the common reasons for proxy IP blocking?

Many users have encountered sudden failures when using proxy IPs, and there are two common reasons for this:The target server recognizes the proxy characteristics of the IP, such as detecting that the IP segment belongs to a data center rather than a real home network; orThe same IP is used repeatedly by multiple people with high frequencyFor example, in a crawler scenario, the failure to change the IP in a timely manner leads to the triggering of the anti-crawler mechanism. Residential proxy IPs can effectively reduce the probability of being recognized due to their real home broadband characteristics.

How to determine if a proxy IP is blocked?

Be wary of IP blocking when the following phenomenon occurs:
1. Target site returns 403/503 error code
2. Suddenly longer request response times
3. CAPTCHA blocking after several consecutive operations
Recommended UseIP health check API provided by ipipgoThe proxy IP availability is monitored in real time and the replacement mechanism is automatically triggered when an anomaly is detected.

Four steps to fast IP replacement

Switching in seconds is possible with the ipipgo service:
Step one:Enable in the consoledynamic rotation schemeSetting up automatic IP switching rules for IP failures
Step two:Bind business APIs to ipipgo's end nodes
Step Three:Add an IP replacement trigger parameter to the request header (e.g. X-Refresh-IP)
Step Four:View IP change records and success rates via log monitoring

Practical tips for long-lasting proxy IP use

- Mixed use of static and dynamic IPs: static IPs are assigned to services that need to maintain sessions, and dynamic IPs are used for regular requests.
- Setting reasonable request intervals: it is recommended that IPs be actively changed every 50-100 requests.
- enableGeolocation decentralization algorithm for ipipgoAutomatically selects residential IP pools for different countries/regions
- Combined with browser fingerprint camouflage technology to reduce the risk of being identified by association

High Frequency Questions and Answers (QA)

Q: Why do I still get blocked after changing my IP?
A:Possibly due to the fact that the new IP has been overused by other users, it is recommended to prioritize ipipgo'sExclusive Residential IPservice, such IP resources are only used by a single user, effectively guaranteeing the purity.

Q: How much IP reserve is needed for enterprise-level business?
A:According to ipipgo's experience of serving 3000+ enterprises, average daily IP demand = total number of tasks / (number of times a single IP is available per day). For example, if you need to fulfill 100,000 requests per day, and a single IP is limited to 500 times per day, you will need 200 dynamic IPs to rotate.

Q: How do I verify the authenticity of a proxy IP?
A:Log in to the ipipgo backend to useIP TraceabilityYou can check the details of the IP such as ASN number, registration organization, network type, etc. The residential IP will clearly show the operator to which the home broadband belongs.
