마크베이스는 네트워크 데이터 타입을 지원함과 동시에 SELECT 문에서 사용할 수 있는 함수들을 지원한다.

  • IPv4 형식 : 4바이트 주소 타입

  • IPv6 형식 : 16바이트 주소 타입

  • 네트워크 마스크 : IPv4  또는 IPv6 에 대한 네트워크 마스크 지정 형식(/비트수)

네트워크 마스크
네트워크 마스크는 특정 주소가 특정한 네트워크에 포함되는지를 지정하는 표현 형식이다. 마크베이스는 네트워크 마스크 타입과 관련 연산자를 지원한다.
네트워크 마스크의 표현 형태
일반 네트워크 표현과 마찬가지로 네트워크 주소 마지막에 / 기호와 비트 개수를 표현하는 형식으로 나타낸다.
 Code Block
'192.128.0.0/16' 
'FFFF::192.128.99.0/32'
네트워크 마스크 연산자
CONTAINS
이 연산자는 왼쪽에 네트워크 마스크와 오른쪽에 네트워크 주소 데이터 타입이 나와야 한다. 즉  입력된 주소가 주어진 네트워크 마스크에 포함되는지를 검사한다. NOT 연산자도 함께 사용할 수 있다.
 Code Block
languagesql
SELECT addr FROM addrtable	WHERE '192.0.0.0/16'	CONTAINS	addr; 
SELECT addr FROM addrtable	WHERE '192.128.99.0/32' NOT CONTAINS	addr;

CONTAINED
CONSTAINS와 반대로, 네트워크 주소가 왼쪽, 네트워크 마스크가 오른쪽이다. 왼쪽 주소가 오른쪽 마스크의 일부인지를 검사한다.
 Code Block
languagesql
SELECT addr FROM addrtable	WHERE addr CONTAINED '192.0.0.0/16'; 
SELECT addr FROM addrtable	WHERE addr NOT CONTAINED '192.128.99.0/32';

마스크 사용 예제
네트워크 마스크 타입을 이용한 검색의 예는 다음과 같다.
