问题
My computer is Windows 8. I used command line to set static IP address by
netsh interface ipv4 set address name="Wired Ethernet Connection" source=static address=1.1.1.1 mask=1.1.1.1 gateway=1.1.1.1
And static DNS by
netsh interface ipv4 add dnsserver name="Wired Ethernet Connection" address=1.1.1.1 index=1
Where 1.1.1.1 in both cases is just for demonstration and was replaced by my real IP.
Edit: As of 2018, 1.1.1.1 is used as a DNS server now.
I want to change from static IP to DHCP now.
I tried
netsh interface ipv4 set address name="Wired Ethernet Connection" source=dhcp
for IP and
netsh interface ipv4 set dnsservers name="Wired Ethernet Connection" source=dhcp
for DNS.
However, only the command for DNS worked.
I then checked with
ipconfig /all
It told me that DHCP was on for Ethernet. However, my previous IP was still there.
Is there any way to set from static to DHCP in command line?
回答1:
netsh interface ipv4 set address name="Wired Ethernet Connection" source=dhcp
ipconfig /renew Wired*
If above ipconfig /renew command does not help, try
netsh interface set interface name="Wired Ethernet Connection" admin=DISABLED
netsh interface ipv4 set address name="Wired Ethernet Connection" source=dhcp
netsh interface set interface name="Wired Ethernet Connection" admin=ENABLED
However, maybe all address, mask and gateway obtained from dhcp could match those defined by source=static previously.
Are there Lease Obtained and Lease Expires properties displayed in the ipconfig /ALL output?
回答2:
For Windows 10
netsh interface ip set address "Ethernet" static 10.10.10.11 255.255.255.0
netsh interface ip set address "Ethernet" source=dhcp
