How to Configure Static IP for VPS and Static Proxy Scenarios

Hands-on with VPS on account booking

A lot of people can't figure out why you need to get a static IP for your VPS, which simply means that you need to get a long-term residence permit for your server. Dynamic IP is like a guerrilla, every reboot will change the address, data collection is particularly easy to reveal. Let's go directly to the dry goods, CentOS system as an example:

nmcli con modify eth0 ipv4.method manual ipv4.addresses 192.168.1.100/24
nmcli con up eth0

Cracking these two lines of command is the equivalent of getting an account on a network card.Note that you have to replace 192.168.1.100 with your real IPIf you are using Ubuntu, you have to go to /etc/netplan/ and find the .yaml configuration file. If you're using Ubuntu, you'll have to look for the .yaml configuration file under /etc/netplan/, and remember to sudo netplan apply after you change it.

Which jobs must use static proxies?

Static agents aren't a silver bullet, but there are a few scenarios where you can't do without them:

To cite a chestnut, with ipipgo's static proxy for e-commerce store management, the same IP login half a month will not trigger the wind control. Their IP pool are directly pulled from the server room dedicated line, much more stable than the home wide proxy.

Configuration Common Pitfalls Fact Sheet

The easiest place for a novice to fall:

1. Wrong subnet mask (/24 not /32)
2. Gateway address not filled in correctly (ask hosting provider for accurate information)
3. DNS server forgetting configuration (223.5.5.5 + 119.29.29.29 double backup recommended)

Recently, I helped a customer to deal with a typical case: after the configuration of static IP found that the Internet can not be connected to the Internet, and finally found that theFireproofing didn't release the new IP.The following is an example of a rule that you can use. Use iptables -L to check the rules and just fill in whatever is missing.

QA First Aid Kit

Q: How do I choose between dynamic and static proxies?
A: need to maintain long-term sessions to choose static (such as the game multi-open), short-term tasks with dynamic (such as the snatch script). ipipgo two are provided, new users to send 5G traffic trial.

Q：Can't connect after configuring static IP?
A: First ping the gateway to see the physical connection, then telnet port 22 to check the ssh service, and finally check the routing table route -n. If you really can't figure it out, you can look for ipipgo's technical support, and their response speed is much faster than the three major carriers.

Q: How do I verify that it is in effect?
A: curl ifconfig.me to see the public IP, or local write a php script output $_SERVER['REMOTE_ADDR']. ipipgo background can also check the real-time connection records, bound domain name, it is recommended to do the DDNS automatic update.

To say a heartfelt, self-built static proxy maintenance costs are not low. Like the IP is to be changed, the server room unplugged to migrate these things, not as directly with ipipgo hosting services. They have an "IP first aid" function is particularly practical, found that the IP abnormalities automatically cut the backup node, than the self-tossing much more worry.
