All time-stamps include a minimum of date, hour, minute and second.
GGSN Address
This field provides the IP address for the control plane of the current serving GGSN, which is equivalent to the configured
ggsn-service address on the GGSN. The standard 3GPP 32.298 offers a choice for the encoding of the address to be either
in binary or text format. The SGSN encodes the address in binary format and includes the Octet String.

IP Address
The IP address format is used by multiple fields in the CDR, such as the GGSN address or the Served PDP address. This
entry is included here to avoid duplication. For the IP address, both the binary and text format and both IPv4 and IPv6 are
specified in 3GPP 32.298.

For custom33 only, served PDP IP address will be in IPV4 or IPV6. The SGSN and GGSN transport interfaces should be
IPV4 encoded.

IPv4 Binary Address
This field contains an IPv4 address in hexadecimal format. Depending on where the field is used in the sequence of the
CDR, it may contain either an SGSN or GGSN address or the PDP IP address of the mobile subscriber. Note the
difference between how the GSN address and the PDP address are encoded. Currently, only IPv4 support is provided.
