In the field of cybersecurity, SSL certificates enable HTTPS encrypted access and trusted identity verification, forming the cornerstone of website security. SSL certificates can be bound to either domain names or IP addresses; IP SSL certificates are used to enable HTTPS encryption for IP addresses.
1. What is an IP SSL Certificate?
An IP SSL certificate, as the name suggests, is an SSL certificate that enables HTTPS encryption for IP addresses. It can also be called an IP HTTPS certificate. IP SSL certificates establish an encrypted communication channel between the server and client, ensuring the confidentiality, integrity, and security of data transmission, thus solving the data transmission security problem between IP addresses and the server.
2. What are the functions of an IP SSL certificate?
The main function of an IP SSL certificate is to implement HTTPS encryption for IP addresses, ensuring the confidentiality and integrity of data transmission and preventing data leakage or tampering; it also enables trusted authentication of the identities of both communicating parties, preventing phishing and impersonation.
3. What types of IP SSL certificates are there?
IP SSL certificates are divided into different types based on the verification method and the number of IP addresses protected.
According to Verification Method:
DV (Distributed Verification): Only requires verification of IP ownership; issuance is fast, taking only a few minutes.
OV (Open Verification): Requires verification of both IP ownership and company information; offers higher security and is generally issued within 1-3 business days.
Based on the number of IPs protected:
A single IP SSL certificate protects one IP address and supports HTTPS for that IP address;
Multiple IP SSL certificates protect multiple IP addresses and support HTTPS for multiple IP addresses.
4. Which CAs can issue IP SSL certificates?
Currently, many CAs on the market, such as Digicert, Sectigo, PositiveSSL, GlobalSign, and CFCA, can issue IP SSL certificates.
5. Can I apply for an IP SSL certificate on an internal network?
Yes. While most CAs currently support encryption of public IP addresses, some brands can also issue certificates for internal IP addresses.
6. In what scenarios can IP SSL certificates be used?
IP SSL certificates are primarily used in scenarios where services are provided via IP addresses, such as internal systems, intranet portals, enterprise intranet servers, IoT devices, and temporary testing environments.
7. How much does an IP SSL certificate typically cost?
Prices vary depending on the brand and type of IP SSL certificate, ranging from a few dollars to several dollars.
8. What are the requirements for applying for an IP SSL certificate?
The main requirements for applying for an IP SSL certificate are: the applicant must have management rights over the IP address; the applicant can be a company/organization or an individual.
