Hi, I am using EM7430 model. Can anyone tell the format of AT+CGCONTRDP output? Does it have gateway, IPv6 DNS servers? AT+CGCONTRDP +CGCONTRDP: 1,5,[airtelgprs.com](http://airtelgprs.com),100.78.51.75,36.1.73.0.98.232.190.225.54.43.95.76.246.80.188.217,9.0.80.0 254.128.0.0.0.0.0.0.0.0.0.0.0.0.0.1,117.96.122.40 36.1.73.0.0.80.0.9.0.0.0.0.0.0.1.140,122.175.1.5 36.1.73.0.0.80.0.9.0.0.0.0.0.0.0.117 OK ---

Thank you for sharing the links. IPv6 global address and link local address acquired on interface by udhcpc are not matching with AT+CGPADDR, AT+CGCONTRDP output. So, I have doubt that whether the exhibited IPv6 DNS1 and IPv6 DNS2 are correct or not. How to get gateway information for both IPv4 and IPv6 using AT commands? ![Screenshot from 2023-06-09 14-50-53](https://us1.discourse-cdn.com/flex025/uploads/sierrawireless/original/2X/1/15e3d34e5aa40834346cd139a43dd9d0f82c65e6.png) cell0 Link encap:Ethernet HWaddr C2:53:7D:26:C4:08 inet addr:100.101.168.125 Bcast:100.101.168.127 Mask:255.255.255.252 inet6 addr: fe80::c053:7dff:fe26:c408/64 Scope:Link inet6 addr: 2401:4900:494e:a12b:c053:7dff:fe26:c408/64 Scope:Global UP BROADCAST RUNNING NOARP MULTICAST MTU:1400 Metric:1 RX packets:1148 errors:917 dropped:0 overruns:0 frame:0 TX packets:87 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:74967 (73.2 KiB) TX bytes:26821 (26.1 KiB) AT+CGPADDR +CGPADDR: 1,100.101.168.125,36.1.73.0.73.78.161.43.0.1.0.1.198.236.135.39 +CGPADDR: 2,0.0.0.0,0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0 OK AT+CGCONTRDP +CGCONTRDP: 1,5,[airtelgprs.com](http://airtelgprs.com),100.101.168.125,36.1.73.0.73.78.161.43.0.1.0.1.198.236.135.39, 254.128.0.0.0.0.0.0.0.0.0.0.0.0.0.5,117.96.122.70 36.1.73.0.0.80.0.9.0.0.0.0.0.0.2.10,117.96.122.40 36.1.73.0.0.80.0.9.0.0.0.0.0.0.1.140 OK global ipv6 (AT+CGCONTRDP): 2401:4900:494e:a12b:0001:0001:c6ec:8727 local ipv6 (AT+CGCONTRDP): fe80::0005 ---

Here says udhcpc is ipv4 only [https://busybox.busybox.narkive.com/ck6iEtcV/udhcpc-and-ipv6](https://busybox.busybox.narkive.com/ck6iEtcV/udhcpc-and-ipv6) Have you tried dhclient -6?
