Method toAddrString

output/java_guava/1.4.19/InetAddresses.java:346–360

Returns the string representation of an InetAddress. For IPv4 addresses, this is identical to InetAddress#getHostAddress(), but for IPv6 addresses, the output follows RFC 5952 section 4. The main difference is that this method uses

(InetAddress ip)

  public static String toAddrString(InetAddress ip) {
    Preconditions.checkNotNull(ip);
    if (ip instanceof Inet4Address) {
      // For IPv4, Java's formatting is good enough.
      return ip.getHostAddress();
    }
    Preconditions.checkArgument(ip instanceof Inet6Address);
    byte[] bytes = ip.getAddress();
    int[] hextets = new int[IPV6_PART_COUNT];
    for (int i = 0; i < hextets.length; i++) {
      hextets[i] = Ints.fromBytes((byte) 0, (byte) 0, bytes[2 * i], bytes[2 * i + 1]);
    }
    compressLongestRunOfZeroes(hextets);
    return hextetsToIPv6String(hextets);
  }
