计算IP列表

IPV4

1、需要的jar包

			<dependency>
                <groupId>cn.hutool</groupId>
                <artifactId>hutool-all</artifactId>
                <version>5.7.7</version>
            </dependency>

2、代码示例

    /**
     * 获取IPV4 CIDR形式下所有的ipv4
     *
     * @param cidr IPV4的CIDR格式 （192.168.1.0/24）
     */
    private static R getIpsV4ByCidr(String cidr) {
        String ip = cidr.split("/")[0];
        int mask = Integer.parseInt(cidr.split("/")[1]);
        String ipFrom = Ipv4Util.getBeginIpStr(ip, mask);
        String ipTo = Ipv4Util.getEndIpStr(ip, mask);
        if (Ipv4Util.countByIpRange(ipFrom, ipTo) > 1024) {
            return R.warn("最多可以支持1024个IP");
        }
        return R.ok().addData(Ipv4Util.list(ip, mask, true));
    }

    /**
     * 获取IPV4 区间范围下所有的ipv4
     *
     * @param ipFrom IPV4的起始ip
     * @param ipTo   IPV4的结束ip
     */
    private static R getIpsV4ByRange(String ipFrom, String ipTo) {
        if (Ipv4Util.countByIpRange(ipFrom, ipTo) > 1024) {
            return R.warn("最多可以支持1024个IP");
        }
        return R.ok().addData(Ipv4Util.list(ipFrom, ipTo));
    }

IPV6

1、需要的jar包

		<dependency>
            <groupId>com.googlecode.java-ipv6</groupId>
            <artifactId>java-ipv6</artifactId>
            <version>0.17</version>
        </dependency>

2、代码示例

/**
     * 获取IPV6 CIDR形式下所有的ipv6
     *
     * @param cidr IPV6的CIDR格式 （fe80::2001/64）
     */
    private static R getIpsV6ByCidr(String cidr) {
        List<String> ipv6List = Lists.newArrayList();
        IPv6Network network = IPv6Network.fromString(cidr);
        if (network.size().compareTo(new BigInteger(String.valueOf(1024))) > 0) {
            return R.warn("最多可以支持1024个IP");
        }
        network.forEach(e -> ipv6List.add(e.toString()));
        return R.ok().addData(ipv6List);
    }

    /**
     * 获取IPV6 区间范围下所有的ipv6
     *
     * @param ipFrom IPV6的起始ip
     * @param ipTo   IPV6的结束ip
     */
    private static R getIpsV6ByRange(String ipFrom, String ipTo) {
        List<String> ipv6List = Lists.newArrayList();
        IPv6AddressRange ipv6Range = IPv6AddressRange.fromFirstAndLast(IPv6Address.fromString(ipFrom), IPv6Address.fromString(ipTo));
        if (ipv6Range.size().compareTo(new BigInteger(String.valueOf(1024))) > 0) {
            return R.warn("最多可以支持1024个IP");
        }
        ipv6Range.forEach(e -> ipv6List.add(e.toString()));
        return R.ok().addData(ipv6List);
    }

IP校验

IPV4
