This dnsseeder implementation is missing a major feature of sipa's dnsseeder. Filtering by service bits.
Thex49service bit shows that a node supports NODE_NETWORK | NODE_WITNESS | NODE_COMPACT_FILTERS, and this could be requested like this:

$ nslookup x49.seed.bitcoin.sprovoost.nl
Server:		1.1.1.1
Address:	1.1.1.1#53
