Please Fix Broken dhcp-server-identifier Advertisement (or allow the current one to accept unicast DHCP Requests)
My router is currentlyserved an IPv4 address from Xfinity via DHCP with 220.127.116.11 designated as the dhcp-server-identifier in the lease. However, this server is not responding to DHCP unicast requests. As a result, my router has to fallback to using the 255.255.255.255 broadcast to renew its lease before it expires and an entirely (?) different server responds. Here's a copy-paste from wireshark illustrating the issue.
|26||344.424617||<my-public-ip>||18.104.22.168||DHCP||342||DHCP Request - Transaction ID 0x70181f64|
|27||362.161344||<my-public-ip>||22.214.171.124||DHCP||342||DHCP Request - Transaction ID 0x70181f64|
|28||382.648518||<my-public-ip>||255.255.255.255||DHCP||342||DHCP Request - Transaction ID 0x70181f64|
|29||382.672195||126.96.36.199||<my-public-ip>||DHCP||372||DHCP ACK - Transaction ID 0x70181f64|
This is pretty lazy network design and is starting to lead to issues where 188.8.131.52 isn't responding in a timely fashion and my lease drops (likewise breaking my connection temporarily), especially because the lease times lately have been smaller for "reasons". Can a network engineer at Xfinity please update the server at 184.108.40.206 to respond to unicast DHCP requests or else update the dhcp-server-identifier to the correct IP?
