forwarders (IPv6)

[Darcy Kevin (FCA)]

That's not a valid IPv6 address representation. You probably mistyped a double colon as a single colon in the middle of the address.

(RFC 4291)

2.2.  Text Representation of Addresses

   There are three conventional forms for representing IPv6 addresses as
   text strings:

   1. The preferred form is x:x:x:x:x:x:x:x, where the 'x's are one to
      four hexadecimal digits of the eight 16-bit pieces of the address.
      Examples:

         ABCD:EF01:2345:6789:ABCD:EF01:2345:6789

         2001:DB8:0:0:8:800:200C:417A

      Note that it is not necessary to write the leading zeros in an
      individual field, but there must be at least one numeral in every
      field (except for the case described in 2.).

   2. Due to some methods of allocating certain styles of IPv6
      addresses, it will be common for addresses to contain long strings
      of zero bits.  In order to make writing addresses containing zero
      bits easier, a special syntax is available to compress the zeros.
      The use of "::" indicates one or more groups of 16 bits of zeros.
      The "::" can only appear once in an address.  The "::" can also be
      used to compress leading or trailing zeros in an address.

                                                                                                                                                                                - Kevin

Hi,

I added below line to my named.conf to include IPv6 addresses to the forwarders list. However I am getting this error "Sep 13 10:33:06 servername named[24778]: [ID 873579 daemon.error] /etc/named.conf:158: expected IP address near '2001:1890:1C04:3000:0CB7:4432'"

"forwarders { 12.227.230.4; 12.227.230.10; 12.183.68.50; 12.183.68.51; 12.71.76.50; 12.71.76.51; 2001:1890:1C04:3000:0CB7:4432; 2001:1890:1C04:3000:0CB7:4433; 2001:1890:1C04:3400:0C47:4C32; 2001:1890:1C04:3400:0C47:4C33; };
        forward first;"

Please let know how to add IPv6 addresses to the forwarders list.

Thanks,
