Hello, Colin!
We use hexademical numbers in PTR for VPS/Servers because PTR's like "host-87.118.199.240.domain.ru" so often banned by weird antispam systems by mask \d+\.\d+\.\d+\d+ as home ISP subnets which produce bunch of spam.

Hi Nikolay, I have obvious hit a cultural nerve here, if so I am sorry. At least there is communication on some level, Chinese colleagues would not even bother to respond to aid debug.
Be that as it may, why not use either normal decimal numbers or normal characters to show what a normal person would understand instead of having to convert the shown output ?

Are Roman numerals allowed in DNS? Because I know some people also do them.

Because looks strange especially if the traffic is 100% bad Best practice says avoid such info in records as does not aid debug since mix of dec and hex
