Getting ipv4 instead of ipv6 in jsf
If you get an IPv6 address then IPv6 is being used. IPv4 and IPv6 are different protocols, and the client chooses which one to use when both are available. If you want the client's IPv4 address then you can force them to use it by not advertising the IPv6 address in DNS. That would be a bad idea though with the increasing deployment of IPv6. Supporting both is good, so it is better to deal with clients using IPv6.

Convert ipv4 & ipv6 both into number
INET6_ATON() will convert both ipv4 and ipv6. As you already know, you need MySQL version 5.6.x or higher. The catch is to use only INET6_ATON() and INET6_NTOA(). The column which will store the the converted IPs will be of VARBINARY(16) type. SELECT INET6_NTOA(INET6_ATON("192.168.1.1")); SELECT INET6_NTOA(INET6_ATON("2001:db8::1")); Remember that the ip column from test_table is VARBINARY(16);

qt dual-stack ipv4 & ipv6 application
Definitely create a local IPv6 network environment. A lot of things work the same in IPv6 as in IPv4, but a lot of other things are different. When developing applications that use IPv6 you should have some hands-on experience. You wouldn't expect someone who has never used IP to develop an application that uses IPv4, would you? Some key differences: IPv6 addresses are written in hexadecimal IPv6 hosts will probably have multiple addresses An IPv6 address that starts with fe80:This is the link-local address. Every IPv6 hosts has one for every interface it has. Link-local addresses exist on every link (ethernet segment, LAN) and they use the same address range on each LAN. It is therefore impossible to route them, but they are very useful when communicating only within the LAN. One or m

PHP IPv4 and IPv6 function to store in a database
You're viewing the address in binary form. "&" is UTF-8 0x26, 0xf0 and 0xd0 are invalid UTF-8 (displayed as "�"), "Q" is UTF-8 0x51, and the other bytes have a null display. Encode the bytestring as hex before storing (and then you can treat IPv4 addresses exactly the same way).

How to parse IP address blocks IPv4 / IPv6
When coming up with a unified IP address representation, it is important to realize that IPv4 addresses occupy 4 bytes and IPv6 addresses require 16 bytes. A naive wrapper implementation would use a union plus an enum discriminator to indicate the address type. Fortunately, this is not necessary because there exists an unambiguous representation of an IPv4 address within an IPv6 address. Keeping this in mind, your IP address wrapper class could look like this: class address { /// Top 96 bits of v4-mapped-addr. static std::array<uint8_t, 12> const v4_mapped_prefix = {{ 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0xff, 0xff }}; public: address() = default; bool is_v4() const { return std::memcmp(&bytes_, &v4_mapped_prefix, 12) == 0; } private: std::array<uint8_t,

Galssfish install on CentOS not binding ipv4 port
You may find Glassfish is bound to IPv4 (and IPv6) but is being blocked by the iptables firewall settings: As root: /etc/init.d/iptables stop Then try accessing Glassfish via IPv4.

Getting number of IPv6 addresses from Ipv6 CIDR in PHP
An IPv6 address has 128 bits, of which (slightly simplified) a number are dedicated to network address, and the rest are dedicated to host addresses. In your case, 32 bits are dedicated to the network part (/32), so the other 96 are dedicated to host addresses. 2^(128-32) = 2^96 = 79228162514264337593543950336 hosts

Conversion IPv6 to long and long to IPv6
An IPv6 address is a 128-bit number as described here. A long in Java is represented on 64 bits, so you need another structure, like a BigDecimal or two longs (a container with an array of two longs or simply an array of two longs) in order to store an IPv6 address. Below is an example (just to provide you an idea): public class Asd { public static long[] IPToLong(String addr) { String[] addrArray = addr.split(":");//a IPv6 adress is of form 2607:f0d0:1002:0051:0000:0000:0000:0004 long[] num = new long[addrArray.length]; for (int i=0; i<addrArray.length; i++) { num[i] = Long.parseLong(addrArray[i], 16); } long long1 = num[0]; for (int i=1;i<4;i++) { long1 = (long1<<16) + num[i]; } long long2 = num[4]; for (int i=5;i<8;i

Forcing HttpUrlConnection to ipv4 only
Please don't force the application to use IPv4. We are deploying networks that have IPv6-only connectivity (with NAT64/DNS64) and IPv4-only applications will break on such networks. The world is running out of unused IPv4 addresses, and parts of the world (Asia, Europe, Middle East) are already out. To solve this please look at RFC 6555: Happy Eyeballs. It describes an algorithm that will try IPv6 first but falls back to IPv4 so quickly that the user will hardly notice it (or usually won't notice it at all). Unfortunately I don't know of a good Java implementation you could use on Android, but I hope others will be able to point you in the right direction. (or you can be the first to write an open source implementation and gain fortune and fame that way (well, fame at least ;))

Python urllib2 force IPv4
Not directly, no. So, what can you do? One possibility is to explicitly resolve the hostname to IPv4 yourself, and then use the IPv4 address instead of the name as the host. For example: host = socket.gethostbyname('example.com') page = urllib2.urlopen('http://{}/path'.format(host)) However, some virtual-server sites may require a Host: example.com header, and they will instead get a Host: 93.184.216.119. You can work around that by overriding the header: host = socket.gethostbyname('example.com') request = urllib2.Request('http://{}/path'.format(host), headers = {'Host': 'example.com'}) page = urllib2.urlopen(request) Alternatively, you can provide your own handlers in place of the standard ones. But the standard handler is mostly just a wrapper aroun

How to use geoip data for IPv6?

For example: $database = (strpos($ip, ":") === false) ? "GeoIP.dat" : "GeoLiteCityv6.dat"; $gi = geoip_open($database, GEOIP_STANDARD); The rest would be the same as before. That said, you might want to consider refactoring so that you aren't opening and closing the database with each call.

IPAddress.HostToNetworkOrder with IPv6
The purpose of converting an IP address to host byte order is so that you can do arithmetic on it using the CPU's normal integer types. For example, in IPv4: network_base_address = address & (0xffffffff ^ ((1 << (32-prefix_length)) - 1) Due to the large size of IPv6 addresses and the rarity of CPU native types that are that big, it was not expected that this kind of arithmetic would be performed on IPv6 addresses. Instead, you can manipulate the original IP address (in network byte order) stored as an array of 16 bytes. For example, while the usual implementation of the C macro IN_MULTICAST (for IPv4) works by bitmasking the integer value of the IP address, the usual implementation of the C macro IN6_IS_ADDR_MULTICAST does its job not by treating the IP address as an integer

Does the idea of private ip address in ipv6?
If you are just setting up a private local network for development/testing and don't have any actual IPv6 connectivity of your own (or your ISP is stupid and only gave you a /64) then unique local addresses will work fine for you. However, unique local addresses cannot be used for connectivity to the global Internet. If you need this, you should get global addresses and a proper firewall (as NAT is not needed and strongly discouraged in IPv6). To get a /48 ULA prefix, visit this generator and throw in a MAC address. (Using a MAC address to generate the prefix is specified by RFC 4193, which defines unique local addresses.)

Pseudo header fields for IPV6 packets
RFC 2460 section 8.1 specifies all this. Some highlights: When determining the pseudo-header destination address when extension headers that change the destination address are used you use the destination address that the recipient would see: If the IPv6 packet contains a Routing header, the Destination Address used in the pseudo-header is that of the final destination. At the originating node, that address will be in the last element of the Routing header; at the recipient(s), that address will be in the Destination Address field of the IPv6 header. When determining the upper layer packet length you don't count any extension headers, only the final (upper layer) header and its data: The Upper-Layer Packet Length in the pseudo-header is the length of the upper-layer h

Basically RFC 4941 claims temporary addresses must: Have a Valid Lifetime less than the "Public" Address Have a Preferred Lifetime less than the "Public" Address So for C++, when using a function like GetAdaptersAddresses you can look in the PIP_ADAPTER_ADDRESSES struct for the _IP_ADAPTER_UNICAST_ADDRESS struct and evaluate the ValidLifetime and PreferredLifetime members. After filtering for address type (if you need to know Local-Link vs Public) you can keep a running tally of the largest lifetime. The largest life time (per adapter) should be the public address!
