Centos의 다른 서브넷에 속하는 영구 IP 별칭을 만드는 방법

나는 팔로우한다이것내 centos 6.5 시스템에 여러 개의 별칭 IP를 연결하고 생성했지만 이러한 모든 IP는 동일한 서브넷에 속합니다.

내가 가진 것:

내 컴퓨터: eth0, 10.91.56.3
IP 별칭 1: eth0: 1, 10.91.56.4
IP 별칭 1: eth0: 2, 10.91.56.5
IP 별칭 1: eth0: 3, 10.91.56.6
IP 별칭 1: eth0: 4, 10.91 .56.7

이제 내 컴퓨터에 다른 서브넷에 속하지만 더 많은 별칭 IP를 만들고 싶습니다.

내가 원하는 것은:

내 컴퓨터: eth0, 10.91.56.3
IP Alias1:eth0:1, 10.91.56.4
IP Alias1:eth0:2, 10.91.56.5
IP Alias1:eth0:3, 10.91.56.6
IP Alias1:eth0:4, 10.91.56.7
IP Alias1 :eth0:5, 10.91.57.4
IP 별칭1:eth0:6, 10.91.58.5
IP 별칭1:eth0:7, 10.91.59.6
IP 별칭1:eth0:8, 10.91.60.7

어떻게 이를 달성할 수 있나요?
