For this challenge, the clue was nameserver. Get into interactive nslookup then set the type to any then search the domain for the flag.

```
root@kali:~/Downloads# nslookup
> set type=any
> jh2i.com
Server: 10.0.2.3
Address: 10.0.2.3#53

Non-authoritative answer:
Name: jh2i.com
Address: 161.35.252.71
jh2i.com nameserver = ns-cloud-a1.googledomains.com.
jh2i.com nameserver = ns-cloud-a2.googledomains.com.
jh2i.com nameserver = ns-cloud-a3.googledomains.com.
jh2i.com nameserver = ns-cloud-a4.googledomains.com.
jh2i.com
origin = ns-cloud-a1.googledomains.com
mail addr = cloud-dns-hostmaster.google.com
serial = 48
refresh = 21600
retry = 3600
expire = 259200
minimum = 300
jh2i.com rdata_99 = "flag{next_year_i_wont_use_spf}"
