Proxy Server Access Control_IP Whitelist + Time Period Restriction

I. Why do we need "IP whitelisting + time period" double insurance?

Many enterprises have encountered this situation: obviously set up IP whitelisting, but the server is still abnormally logged in; or a specific period of time when the business volume surge, the proxy IP suddenly failed. This shows that there are two loopholes in relying solely on whitelisting:Fixed IPs are easily tagged with features,Persistent access triggers risk controlThe

Through ipipgo proxy service testing, it was found that after combining dynamic IP whitelisting with the time period policy, the server's anomalous accesses dropped by 76%.This combination not only guarantees the legitimate access identity, but also disperses the frequency of requests through the time dimension, which is especially suitable for the need ofBalancing security and stabilityof business scenarios.

II. Three steps to build an intelligent access system

Step 1: Create a base whitelist library
Using ipipgo's static residential IP as the core whitelist, it is recommended to select an IP segment that matches the business region. For example, e-commerce platforms choose residential IPs in user-intensive areas to ensure access success rates and to match normal user network characteristics.

Step 2: Configure the Time Access Window
In the server firewall settings, set the effective time period for different IP groups. For example:

Step 3: Setting up the automatic switching mechanism
Through ipipgo's API interface, we can develop timed tasks to automatically switch proxy IPs at specified times, for example, changing the export IP of the crawler service at 8:00 pm every night, to avoid IP blocking and maintain business continuity.

Third, avoid three common configuration misunderstandings

Myth 1: The more whitelisted IPs the better
Measurements have shown that with more than 50 whitelisted IPs, management costs rise 371 TP3T. ipipgo is recommended forIP Quality Scoring System, screen for highly anonymized residential IPs and keep it to 20 or less.

Myth 2: Time period settings are too mechanical
Instead of simply dividing by whole points, you should incorporate business traffic fluctuations. By ipipgo'sTraffic Monitoring Panel, view historical request spikes, and set elastic time periods.

Myth 3: Ignoring Protocol Adaptability
Some firewalls have better support for the socks5 protocol, while API interfaces may require the http protocol. ipipgo supportFull protocol auto-adaptation, ensuring protocol compatibility in different scenarios.

IV. Typical problem solutions (QA)

Q: How do I whitelist a dynamic IP?
A: Using ipipgo'sIP Binding ServiceThe following is an example of how to whitelist dynamic IPs. which can lock dynamic IPs to a specified area range and generate verifiable IP segments to be added to the whitelist.

Q: What about time zone confusion for multinational business?
A: Open in the ipipgo consoleAutomatic time zone calibrationfunction, the system will automatically convert the local time according to the target server location.

Q: How do I respond in case of unexpected traffic?
A: Setting up your ipipgo account in advanceAlternate IP Pool Trigger Rules, when the request delay of the primary IP pool exceeds 200ms, the standby IP is automatically enabled.

V. The advanced play of security protection

For financial-grade security needs, stacking is recommended:

1. Fingerprint Browser + Proxy IP Combo
2. Change IP address per session
3. Setting up multiple time verification policies

via ipipgo'sResidential IP Rotation SystemIt can realize automatic IP change every hour without interrupting the session, and form a three-dimensional protection network with time policy.

This combination of solutions has successfully intercepted 99.2% of malicious crawling behavior in a bank system test, while ensuring the access experience of normal users. By reasonably utilizing the characteristics of proxy IP, it is possible to build a reliable security system without reducing business efficiency.
