As I pointed out some time ago, this code will grab MAC address of a Cisco VPN virtual adapter(which is a peace of software btw.). Thus, in a strict sense your statement “read the address regardless of the changes another program makes” applied to this particular peace of code is not correct. The only point I am trying to make here is that one should not blindly rely on this MAC address detection technique for sensitive things like identifying machines for software licensing purposes – it can be easily forged. MAC address is the least of your worries regarding privacy in the internet. Sender and receiver MAC addresses are only used inside of your “last hop” Ehternet LAN in the most typical scenario. Download video dragon ball gt episode 1 aub indo. Packets that you receive and send are identified by IP addresses (which will also often be not your direct LAN IP, but an IP of your router + NAT). Furthermore, MAC addresses will be discarded as soon as your packet leaves Ethernet transport network and other Layer 2 technology is used as they only make sense in this limited domain. Matching IPv4 Addresses Problem You want to check whether a certain string represents a valid IPv4 address in 255.255.255.255 notation. Optionally, you want to convert. - Selection from Regular Expressions Cookbook [Book]. Iview hd hack account. Internal Android camera (front and back) is also supported to use the app as an IP camera.

I have a string that represents a MAC address, but does not show the higher-order byte for each address term if it is zero. That is, instead of an address of the form 00:11:22:33:44:55, I would have an address of the form 0:11:22:33:44:55; instead of an address of the form 00:1b:17:00:0b:31, it has the form 0:1b:17:0:b:31. I would like to convert a string missing a MAC address's high-order byte (if that high-order byte is zero) to a string that explicitly includes its high-order byte. Obviously, I could split the incoming string on: and then walk through each element. But I thought it might be cleaner/faster to do it with a regular expression (specifically string's method). However, the regular expression that I wrote doesn't work. As an example, String original = '0:1b:17:0:b:31'; String replaced = original.replaceAll('(^|:)([0-9a-f])(:|$)','$10$2$3'); System.out.println(replaced); prints 00:1b:17:00:b:31. Essentially, it misses inserting the higher-order byte for the last b. I think this is because the regular expression that I'm using has overlapping matches: the colon used to delimit the end of one match must also be used to delimit the beginning of a subsequent match if there are two or more entries missing high-order bytes. Is there a way to allow for overlapping matches using Java's regular expressions? Alternately, is there a regular expression that I'm not thinking of that could be used here? Or do I really have to take a multi-line approach (e.g., string-splitting and iterating, using the above regular expression multiple times until the result is the same is the input, etc.).
