IPv6 disable하기

IPv6 disable하기

 

1. DNS를 쓸 경우 /etc/netsvc.conf에 hosts=local4,bind4 로 설정되어 있는지 확인

 

2. routing table에 ipv6환경이 설정되어 있는지? 있다면 해당 interface에서 항목 삭제

 

ex) netstat -rn : lo0에서 ipv6가 사용중인 경우

 

Route tree for Protocol Family 24 (Internet v6):
::1%1              ::1%1             UH        1        96 lo0      -      -

 

 1)    

.....    lsattr -El lo0
.....

mtu           16896     Maximum IP Packet Size for This Device     True
netaddr       127.0.0.1 Internet Address                           True
netaddr6      ::1       IPv6 Internet Address                      True

 

=> #chdev -l lo0 -a netaddr6='' 로 변경 후,

 

.....    lsattr -El lo0
.....

mtu           16896     Maximum IP Packet Size for This Device     True
netaddr       127.0.0.1 Internet Address                           True
netaddr6                IPv6 Internet Address                      True

 

 2)  #ifconfig lo0 inet6 ::1 delete  

lo0: flags=e08084b,c0<UP,BROADCAST,LOOPBACK,RUNNING,SIMPLEX,MULTICAST,GROUPRT,64BIT,LARGESEND,CHAIN>
        inet 127.0.0.1 netmask 0xff000000 broadcast 127.255.255.255
         tcp_sendspace 131072 tcp_recvspace 131072 rfc1323 1

=> inet6 항목이 제거됨
