# TCP.mk Node
1+
## About TCP.mk
2+
3+
`TCP.mk` is an efficient network toolkit designed to help users quickly diagnose and resolve network issues, improving work efficiency. Our toolset covers a wide range of functionalities, from IP queries to network status detection, making it suitable for various network operation and development scenarios.
4+
5+
6+
### Main Features
7+
- **IP Aggregation Query**: Retrieves geographic location information from multiple IP data sources, enabling easy comparison and avoiding inaccuracies from a single data source.
8+
- **Batch IP Query**: Supports querying up to 50 IPs at once.
9+
- **HTTP Status Detection**: Monitors the HTTP status codes of websites or services in real-time, helping users track service availability.
10+
- **TCP Port Detection**: Checks the open/closed status of TCP ports on target hosts.
11+
- **GFW Detection**: Quickly Detect if a Website or IP is Blocked by the Great Firewall of China.
12+
- **Online Dig Command**: Provides an online DNS query tool that supports multiple DNS record types, enabling users to quickly diagnose DNS issues.
13+
- **Dual-Region IP Detection**: Detects the IPs used for accessing domestic and international networks.
14+
- **Global Ping**: Initiates Ping probes from various locations worldwide to comprehensively assess network latency and connectivity.
15+
- **Traceroute**: Initiates route tracing from any global node to precisely analyze network routing.
16+
- **API**: We provide an API interface for IP queries.
17+
18+
### Notice
19+
20+
This project implements the node functionality of TCP.mk. For the full feature set, please visit: [https://tcp.mk](https://tcp.mk)
