IPv4 vs. IPv6 Differences: Dual Protocol Proxy Configuration Comparison

What's the difference between IPv4 and IPv6?

For example, IPv4 is like a small bungalow in an old city, with a maximum of 4.3 billion address plates (actually 2^32), which is not enough for a long time, while IPv6 is a newly built smart apartment building, with a large number of addresses.Assign IP to every grain of sand on Earth(2^128th power). Nowadays, a lot of websites have both addresses hanging around, which forces us to engage in proxies toDual protocols served at the same timeThe

Proxy Configuration Practical Comparison Manual

Let's look at IPv4 proxies first, which everyone is familiar with. Using ipipgo's dynamic residential proxy as an example, 代码里填个http://username:password@gateway.ipipgo.com:端口 will be able to run. But when it comes to IPv6 environments, it's a bit confusing, and it's really just two more steps:

 Detect whether you support IPv6
curl -6 icanhazip.com
 IPv6 proxy format for ipipgo
http://[IPv6 address]:port@username:password

Focus on this.Square bracketed packet IPv6 addressformat, and many newbies fall flat on their faces here. I generally recommend starting with the ipipgo client in theEnable dual-stack modeThe system will automatically select the optimal protocol.

Treading the Pit Record: Blood and Tears of Experience

Last week to help customers debug a crawler project, obviously the proxy configuration of the right but dead can not connect. Later, I realized that the server roomFiber optic cats don't have IPv6 support turned on, tossing around for three hours for nothing. Here to teach you a clay method:

 Windows view protocol support
netsh interface ipv6 show global
 Linux detection commands
ip -6 route show

If it shows"Disabled" or no outputI'm not sure if I'm going to be able to do that, but I'm going to have to find a way to do it. There is also a cold knowledge: now 30%'s mobile network uses IPv6 by default, brothers who do data collection must pay special attention.

ipipgo dual protocol real-world solution

Their agency service is really hassle-free, checking the box directly in the back office"IPv4/IPv6 Dual Stack Access."Just do it. Tested scenarios where two requests are handled at the same time, for example:

Focusing on enterprise level needs, use their homeCross-border PackageRemember to add the X-Forwarded-For parameter in the request header to reduce the CAPTCHA triggering rate of 30%.

A must-see QA trifecta for white people

Q: Why are IPv6 proxies always more expensive than IPv4?
A: The resources are really small! Now the global IPv6 coverage is only about 40%, like certain countries in Africa did not deploy at all. ipipgo's static residence 35 yuan / month is considered a conscientious price, and some factories dare to ask for triple-digit prices.

Q: Will dual protocols be used at the same time for serial numbers?
A: Not if you use the right method. Set the session object in the code and bind the fixed export IP. ipipgo API support?protocol=dual parameter, automatically assigns matching IP pairs.

Q: Is the Enterprise package worth it?
A: Depends on the volume of business! $9.47/GB for that band!Dedicated ASN number, do ad placement must on, can avoid 80% account association problem.

Say something from the heart.

I've been in the proxy business for six years, and I've seen too many people get stuck on protocol issues. Last year, there is an independent site of the old brother, because did not open the IPv6 proxy, lost the South American market for nothing. Now ipipgo's client has been able toAutomatic recognition of protocol environmentsI suggest you guys update to the latest version, don't mess with the money, right?
