Taiwan Vps Native Ip Practical Tutorial Teaches You To Complete Rapid Deployment Configuration

1. Purchase and confirm that Taiwan VPS supports "native IP"

- Select a vendor: Give priority to vendors that indicate that they provide public IPv4 and are not Carrier-NAT (such as some Taiwanese local cloud/host providers).
- Note when placing an order: Confirm whether it is "native IP (directly connected to the public network/independent IP)" and do not select "shared IP/NAT".
- Obtain information: After placing the order, you will receive the IP, gateway, subnet mask, DNS and default password/SSH information of the control panel.

2. Connection and initial login (SSH)

- Open a terminal locally: ssh root@your IP (or use PuTTY). The first connection accepts fingerprints.
- Change the default password: passwd (if necessary, add an administrator account first and disable root login).
- Update system: Ubuntu/Debian: apt update && apt upgrade -y; CentOS: yum update -y.

3. Configure the network card (Ubuntu uses netplan)

- Edit the netplan configuration file: /etc/netplan/01-netcfg.yaml (example):
network: {version: 2, ethernets: {eth0: {dhcp4: no, addresses: [your IP/24], gateway4: gateway, nameservers: {addresses: [8.8.8.8,1.1.1.1]}}}}
- Apply: sudo netplan apply. If there is no netplan, use /etc/network/interfaces instead.

4. Configure the network card (CentOS/RHEL uses ifcfg or NetworkManager)

- Edit /etc/sysconfig/network-scripts/ifcfg-eth0: add IPADDR=your IP, PREFIX=24, GATEWAY=gateway, DNS1=8.8.8.8.
- Restart the network: systemctl restart network or nmcli con reload. Confirm that ip addr shows the new IP.

5. Add additional IPs/aliases and routes

- Temporarily add: sudo ip addr add auxiliary IP/32 dev eth0; permanently please write the corresponding network configuration file.
- If facing routing problems, add static route: sudo ip route add default via gateway dev eth0.

6. Reverse DNS and WHOIS configuration

- Set up PTR (reverse resolution) to your domain name in the provider control panel.
- Check: dig -x your IP or host your IP to ensure that the reverse resolution is effective, which is beneficial to email delivery and reputation.

7. Basic security hardening and firewall

- Change the default SSH port or use public key to log in: Configure in /etc/ssh/sshd_config and restart sshd.
- Install firewall: Ubuntu uses ufw (ufw allow 22/tcp; ufw enable), CentOS uses firewalld. Install fail2ban to prevent brute force cracking.

8. Test network connectivity and confirm external IP address

- Local test: ping -c 4 8.8.8.8; traceroute to see the routing path.
- Confirm the external IP: curl -s https://ipinfo.io/ip or curl -s https://ifconfig.me; if it is consistent with the control panel IP, it indicates that it is the native IP.

9. Frequently asked questions and troubleshooting techniques

- Unable to access the Internet: Check whether the default route and gateway are correct, and check ip route.
- DNS cannot be resolved: check whether /etc/resolv.conf and nameserver are valid. If the provider has a private network, you need to set up static routing or contact support.

10. Question: How to confirm whether my Taiwan VPS is a native IP and not NAT?

Q: How can I confirm whether my Taiwan VPS is a native IP and not a NAT? Answer: Use curl ipinfo.io/ip to return the IP from the VPS consistent with the IP assigned on the control panel; at the same time, use another host on the external network to traceroute to the IP to see if the routing path directly passes through the public network ISP. If the supplier clearly states "independent public network IPv4/native IP" and there is no shared NAT network segment, it is native.

11. Question: How to ensure that emails and services are not blocked after the configuration is completed?

Q: How to ensure that emails and services are not blocked after the configuration is completed? Answer: Set up the correct PTR reverse DNS, configure SPF/DKIM/DMARC records, ensure that the server does not engage in abusive behavior, and ensure consistent information through WHOIS/vendor records. If necessary, apply to the email service provider for unblocking or applying for a dedicated IP.

12. Question: What long-term maintenance matters do I need to pay attention to after the deployment is completed?

Q: What long-term maintenance matters do I need to pay attention to after deployment? Answer: Regularly update system and security patches, monitor bandwidth/traffic, check blacklists, back up important configurations, and regularly audit firewall and SSH access logs to ensure long-term stable availability of native IP.
