Frequently Asked Questions

Internal names include hosts and domains that cannot be registered or resolved in public DNS e.g., server01 or server.local, localhost, etc.

Internal IP addresses cannot be registered for use on public networks. They include IPv4 or IPv6 addresses the Internet Assigned Numbers Authority (IANA) marks as reserved. The most common reserved ranges are 10.0.0.0-10.255.255.255, 172.16.0.0-172.31.255.255, and 192.168.0.0- 192.168.255.255. More information is available here.

SecureNT Intranet SSL Certificate – Single Domain secures an Intranet Server’s Local Host Name, Server Name, internal/public IP Address, or Web page URL using Secure HTTPS protocol.

Certificates are valid for a period ranging from 1 to 10 years. One can install the certificate on unlimited servers. We offer a 90-day Free Single Domain Certificate.

For creating CSR with SAN values (X.509 v3 Extension) it’s important to create a configuration file with the required certificate details. Execute following command in openssl.

openssl req -newkey rsa:2048 -nodes -keyout pvtkey.cer -config config.cnf -out csr.txt -utf8

It will create a Private key (pvtkey.cer) and CSR file (csr.txt).

Sample Configuration file (config.cnf)

[req]
prompt = no
distinguished_name = dn
req_extensions = ext

[dn]
CN = 192.168.2.23
O = Abc Corporation
L = Sydney
ST = New South Walse
C = AU

[ext]
subjectAltName = @alt_names

[alt_names]
IP.1 = 192.168.2.23
IP.2 = 10.12.4.122
DNS.1 = 192.168.2.23
DNS.2 = 10.12.4.22
DNS.3 = sms.abc.local
DNS.4 = localhost

It will generate CSR with CN=192.168.2.23 and 3 SAN values: 10.12.4.122, sms.abc.local and localhost.

Notice that when IP address is there in CN or SAN, we need to put its value against both IP Address and DNS. For others (URL, Servername etc) only DNS value is required.
