If you follow along with the commits for the bitcoin-seeder app, you will find that the line in GetBanTime which compares clientVersion to 31900 was added a couple years earlier than the line in IsGood which compares to REQUIRE_VERSION.

Long story short, it certainly seems like an oversight that the 31900 value was left hardcoded and never updated. In my opinion, both values should be compared against the MIN_PEER_PROTO_VERSION value from version.h.
If you are still confused, feel free to take a look at how I handled this in my generic-seeder clone: https://bitcointalksearch.org/topic/dns-seeder-setup-guide-using-the-generic-seeder-5239304

I'm creating dnsseed based on https://github.com/sipa/bitcoin-seeder. But I got a problem when adapting the seeder software.
The variable "clientVersion" is compared with REQUIRE_VERSION(which is a protocol version) in the function IsGood,
while it is compared with 31900(which seems to be a client version v0.3.19) in the function GetBanTime.
I'm confused. What on earth should "clientVersion" be compared with? Client version or protocol version?
This is the output of bitcoin-cli.
Looking forward reply. Thanks!
The variable "clientVersion" is compared with REQUIRE_VERSION(which is a protocol version) in the function IsGood,
Code:
if (clientVersion && clientVersion < REQUIRE_VERSION) return false;
Code:
if (clientVersion && clientVersion < 31900) { return 604800; }This is the output of bitcoin-cli.
Code:
$ bitcoin-cli getnetworkinfo
{
"version": 170100,
"subversion": "/Satoshi:0.17.1/",
"protocolversion": 70015,
......
}
