The address is made up of the international data number (IDN), which consists of two fields: the 4 digit data network identification code (DNIC) and the (up to) 10 digit national terminal number (NTN).

The DNIC has three digits to identify the country (one to identify a zone and two to identify the country within the zone) and one to identify the PDN (allowing only ten in each country

Data Network Identification Code.

A data network identification code (DNIC) consists of 4 digits that include:.

Data Country Code (DCC). The first digit identifies a world geographic zone. The second and third digits identify a specific country.

Public Data Network Code (PDN). The fourth digit in the DNIC identifies a specific PDN.

International data number(IDN).
DNIC = 4 digit.
Country = 1+2 (one to identify a zone and two to identify
the country within the zone).
PDN = 1.

NTN = (up to) 10 digit national terminal number.

One to identify zone and two to identify country and zone.

Thank you for information but data link layer difference data link identification code country ENA relationship.

Data network identification code (DNIC) : In the CCITT International X.121 format, the first four digits of the international data number, the three digits that may represent the data country code, and the 1-digit network code, i.e 1, the network digit.

Please explain it with the example.

Please explain whether the answer is 3 or 4?

In the DNIC, the first four digits of the international data number, the three digits that may represent the data country code, and the 1-digit network code, i.e, the network digit.

For suppose.

The DNIC no of the country Germany: 262 2 (packet switched data service).

Here 262 represents data country code & last single digit "2"represents the netwrok digit (packet switched data service) -name of the n/w to which DNIC is located.

The first four digits of the international data number, the three digits that may represent the data country code, and the 1-digit network code, 1, the network digit.

Agree @Karthika.

The NTN identifies the exact network device (DTE, data terminal equipment) in the packet-switched network (PSN) and is often provided as an NUA. There are no rules to the structure of the NTN.
