ipv6

I work on implementing IPv6 support for several applications, but I wondered what are these 2 fields for. There are so few questions about this here so I'm not sure I got it right. About scope ID ( sin6_scope_id ) - well, Q1 , Q2 , Q3 and Q4 gave me idea about the scope ID and I think I get it. So, I'll have to add one more config parameter, to make the scope-id configurable. (I decided to add this here, in case that someone is interested in this). Shortly - scope ID is necessary to uniquely determine which is the device, that should handle the traffic - because there may be several interfaces

have apps, built 2015 and 2014. How can I test them for IPv6? If my apps doesn't support IPv6, what should I do? My apps are using AFNetworking and Alamofire. I'm connecting mostly to domains ( Ex. api.example.com/v1/...). Only 1 app use IP: (ex: 12.12.12.12:3000/api/v1/...). This solution only works if you have an ethernet connection. For creating an iPV6 NAT64 wifi network, follow these steps Step 1 : Open system preferences Step 2 : Open Sharing Step 3 : Click on internet sharing Step 4 : Click Wifi in the ports while pressing option(ALT) key.

when I do this ip = request.env["REMOTE_ADDR"] I get the client's IP address it it. But what if I want to validate whether the value in the variable is really an IP? How do I do that? Please help. Thanks in advance. And sorry if this question is repeated, I didn't take the effort of finding it... EDIT What about IPv6 IP's?? molf Why not let a library validate it for you? You shouldn't introduce complex regular expressions that are impossible to maintain. % gem install ipaddress Then, in your application require "ipaddress" IPAddress.valid? "192.128.0.12" #=> true IPAddress.valid? "192.128.0

I'm changing some tables to store IP addresses as numbers rather than strings. This is simple with IPv4 where the 32 bit address can fit into an integer column. However, an IPv6 address is 128 bits. The MySQL documentation only shows numeric types up to 64 bits ("bigint"). Should I stick with char/varchar for IPv6? (Ideally I'd like to use the same column for IPv4 and IPv6, so I'd prefer not to do this). Is there anything better than using two bigint columns? I would prefer not to have to break the value into upper and lower /64 whenever using the address. I'm using MariaDB 5.1 - if there's a
