Match IPv4 address against pattern or dns

Question

I have a IPv4 address which should be compared against a pattern. A pattern can either be a specific address maybe containing wildcards or a dns.

• *
• ..*.*
• 192.168.*.5
• 206.0.3.4-25
• 45.30.9.101
• www.google.de

I already figured out that the InetAddress/Inet4Address class is the right one. But i cant figure out how to use it with both dns and wildcards. I get pattern and address as strings.

Answer 1

trying using a regular expression.

For numbers (\d{1,3},\d{1,3},\d{1,3},\d{1,3}) For domain, just google regular expression to match domain URL
