I'm a not a network guy but trying to get up to speed with our DNS configuration on this Windows 2008 R2 server.. In the image below I have received advice that the static 10.1.1.0 entry is not required and in fact can cause problems. Is this correct? What does this entry indicated?
Also, the record above (10.1.1.252) is not known to use and does not respond to pings. Given it was last updated in 2015 I'm considering deleting it. Shouldn't these records expire automatically?
