IPv4 and IPv6 Packets: IPv4/IPv6 Proxy Packet Processing Solution

Packet sorter's little secret: How do IPv4 and IPv6 go proxies?

Older drivers who are involved in the network know that there are two types of courier trucks running on the road now: the old IPv4 trucks and the new IPv6 containers. These two models have different manifest formats and different loading methods. For example, IPv4 courier orders can only write 32-bit address, like the old-fashioned landline number, IPv6 address field is full of 128-bit, can be accurate to your home microwave oven's IP address.

Many of you who use proxy services often encounterexpress delivery of goods within a short timeIn the case of IPv6, it's actually improper packet handling. ipipgo's engineers have found that 90%'s connection failures are due to a lack of clarity about the difference between the two protocols. For example, using an IPv4 proxy to handle IPv6 requests is like letting a carriage driver drive a high-speed train.

Loading and unloading guidelines for agency service stations

Our proxy server is like an intelligent sorting center that handles different protocols with the key topreflight access. Here are three practical tips to teach you:

 Python Example: Detecting Protocol Types
import socket

def detect_protocol(ip).
    socket.inet_pton(socket.AF_INET6, ip).
        socket.inet_pton(socket.AF_INET6, ip)
        return "IPv6"
    except socket.error: return "IPv4
        return "IPv4"

This code snippet is like a scanning gun at a courier station that quickly identifies the type of package. Be careful in practice:

1. Dual stack configuration must be on: The server should support both protocols
2. Routing tables to be separated: Separate settings for IPv4 and IPv6 forwarding rules
3. MTU value to be adjusted: The default packet size for IPv6 is 1280 bytes, so don't let big packages get stuck at toll booths!

Diary of a real-world pit stop

Last year, we encountered a typical problem when we did a migration program for an e-commerce company: their crawler program used ipipgo's static residential proxy, and suddenly went on strike collectively after switching to IPv6. Troubleshooting found that theNo handshake on the protocol stack., it's like two couriers speaking different dialects failing to dock. The solution is actually massively simple:

Why choose ipipgo's transfer station?

Our agency service is like a super service area on the highway, three exclusive secrets:

- Hybrid lane design: Automatically recognizes the protocol type without having to switch manually
- Smart Routing Table: Selection of the optimal line according to the protocol type
- Protocol converter: IPv4-only applications can also access IPv6 resources

Take a real case: a short video platform needs to capture both overseas IPv4 and domestic IPv6 resources, using ourTK Private Line PackageAfter that, the data collection efficiency increased by 4 times. Their technical director's exact words were, "This thing is silkier than Dove."

Common QA for white people

Q: My computer shows an IPv6 address, but the proxy keeps failing to connect?
A: 80% of the system stack is not installed properly, in the cmd to knock thenetsh interface ipv6 installtry out

Q: Which package should I choose for enterprise applications?
A: Dynamic residential (enterprise) package is the most stable, more than 9 yuan 1G of traffic, comes with automatic failover function

Q: How do I charge if I want to use both protocols at the same time?
A: All of ipipgo's packages areprotocol-independent billingThe data is billed at a flat rate regardless of which packets are run.

The last nagging sentence: now ipipgo static residential package is doing activities, 35 yuan can be a monthly exclusive IP. need to customize the program can be directly to find technical customer service, reported the secret code "double stack driver" has a surprise (don't ask what, go to ask on the know).
