how to delete IPV6 address by ifconfig up/down

1 New Member
hi all,
I have faced one problem in ifconfig in linux.I used ifconfig command then after i want delete the IPV6 address permanetly by ifconfig up/down, how is it possible plz give me some suggestion...

For Example

fconfig eth0
eth0 Link encap:Ethernet HWaddr 00:13:D3:3F:7F: 37
inet addr:172.16.170 .117 Bcast:172.16.17 0.255 Mask:255.255.25 5.0
inet6 addr: fe80::213:d3ff: fe3f:7f37/64 Scope:Link <- here
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:2055609 43 errors:0 dropped:0 overruns:0 frame:1
TX packets:7425356 76 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:515791587 (491.8 MiB) TX bytes:316878808 6 (2.9 GiB)
Interrupt:193

When fe80::213:d3ff: fe3f:7f37/64 is deleted by ifconfig command
> ifconfig down
> ifconfig up
fe80::213:d3ff: fe3f:7f37/64 apportioned once again

I'm not sure if this is a question about python socket support or sockets in general ... I have a socket server with which I want to accept incoming connections on ipv4 and ipv6. I've found that if I create the listening socket with sock = socket(AF_INET, SOCK_STREAM) it will accept connections on ipv4 (only) and if I create it with sock = socket(AF_INET6, SOCK_STREAM) it will accept connections with ipv6 (only)

I want to determine the outside (non local, a.k.a. 127.0.0.x) ip addresses of my host. It seems that the socket module provides me with some nifty tools for that but I cannot get it to work correctly it seems. Can someone enlightened show a light on this: import socket def getipaddr(hostname='default'): """Given a hostname, perform a standard (forward) lookup and return a list of IP addresses for that host."""
