The exception throws near this 49164 type ID. Using this 8.8.8.8 DNS server.
This appears to be a result of a blank TXT record for the domain not being picked up correctly. DIG output:

Although the order of TXT isn't consistent and therefore breaks at different places, but does appear to be the blank.
Under investigation.
Also sometimes shows 49172 record type - confirmed this seems an error with TXT "" records which should be handled (but aren't!)
Branch emptytxt has a trial fix for this, skips a character ahead when TXT records have a length of 1 (empty string), skipping over char which is causing issue. Testing seems to show no impact on other valid TXT.
Merged to master and passing CI
Release 2.1.1 includes this fix https://packagist.org/packages/purplepixie/phpdns - will keep this open pending testing. @uksarkar thank you very much for finding this and please do try the latest release and let me know how you get on.
@purplepixie thank you for the quick response, it looks ok for now. Maybe you can close the issue now.
Many thanks @uksarkar. Issue resolved with 2.1.1
