Hi,
I'm trying to have EDNS implemented on my network, I installed BIND 9.10.3-P2 which is the latest version these days.
I got it working (I think), but I'm missing something here:
When I dig using 8.8.8.8 I get:
; CLIENT-SUBNET: 5.149.0.0/24/0
Code:
; <<>> DiG 9.10.3-P2 <<>> facebook.com @8.8.8.8 +subnet=5.149.0.0/24
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 22686
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1
;; OPT PSEUDOSECTION:
; EDNS: version: 0, flags:; udp: 512
; CLIENT-SUBNET: 5.149.0.0/24/0
;; QUESTION SECTION:
;facebook.com. IN A
;; ANSWER SECTION:
facebook.com. 279 IN A 173.252.120.68

;; WHEN: Sat Dec 19 12:51:56 EST 2015

But when I dig using my new DNS, I get EDNS: version: 0, but no client-subnet.
Code:
; <<>> DiG 9.10.3-P2 <<>> facebook.com +subnet=5.149.0.0/24

I tried to dig almost everywhere on the internet, and still digging, but nothing so far.
What am I missing here? can someone direct me somewhere helpful?
The DNS packet size on my DNS is 4096 which is ok in terms of EDNS.
Appreciate any kind of help.
