dnsmasq setting clarification - IPv4 address and strict-order

1. On the Setup tab for my account, under Linked IP it lists these DNS servers:

45.90.28.64

45.90.30.64

But under Setup Guide, if you select Linux (or Routers), for dnsmasq (and stubby, knot, etc.) it lists these DNS servers:

45.90.28.0

45.90.30.0

I went with the .0 servers and it seems to be working okay. But I was wondering, maybe I should be using .64, was I given .64 for load-balancing purposes and the guide for dnsmasq just didn't update?

2. In the Setup Guide for dnsmasq it asks for strict-order and lists 45.90.30.0 before 45.90.28.0 (I don't have IPv6 so I left that out). Is the intent to mainly use 45.90.30.0, and only use 45.90.28.0 if it doesn't respond? dnsmasq unfortunately seems to ignore the order, here is the order they appear in my dnsmasq.conf:

server=45.90.30.0
server=45.90.28.0
strict-order

but here is what the log shows on startup

Dec  9 14:00:51 dnsmasq[19282]: using nameserver 45.90.28.0#53
Dec  9 14:00:51 dnsmasq[19282]: using nameserver 45.90.30.0#53
 

and here are the statistics

Dec  9 21:10:16 dnsmasq[19282]: server 45.90.28.0#53: queries sent 20537, retried or failed 2668
Dec  9 21:10:16 dnsmasq[19282]: server 45.90.30.0#53: queries sent 2854, retried or failed 6

So it's definitely preferring 45.90.28.0. I think I would probably get better performance if it would prefer 45.90.30.0 since my ping there is about half what it is to 45.90.28.0

  vultr-sea    27 ms

■ anexia-yto   31 ms  (secondary)

  vultr-yto    32 ms

  vultr-chi    55 ms

  zepto-ymq    59 ms

■ zepto-xrs    65 ms  (primary)

  vultr-sjc    69 ms

  do-sfo       71 ms

  vultr-lax    72 ms

  anexia-lax   73 ms

  zepto-lax    80 ms
 

Not that the performance is bad or anything. But again I was wondering if I should try to prefer 45.90.30.0 for load-balancing purposes or something.

I guess for issue #2 there is probably no fix other than to report it to dnsmasq, or use something else.
