Bollards are an example of a method that is used to prevent motor vehicles from getting too close to building entrances and exits. Bollards are short, sturdy posts that are installed on sidewalks, parking lots, or roads to create physical barriers and control traffic flow. Bollards can be used to protect pedestrians, buildings, or other structures from vehicle collisions or attacks. Bollards can be made of various materials, such as metal, concrete, or plastic, and can be fixed, removable, or retractable.

The administrator should use 172.16.19.241 as an IP address to be in compliance with RFC 1918 standard. RFC 1918 defines three ranges of IP addresses that are reserved for private internets, meaning they are not globally routable on the public Internet and can be used within an enterprise without any risk of conflict or overlap with other networks. These ranges are:

10.0.0.0 - 10.255.255.255 (10/8 prefix) 172.16.0.0 - 172.31.255.255 (172.16/12 prefix) 192.168.0.0 - 192.168.255.255 (192.168/16 prefix)

Out of these ranges, only 172.16.19.241 falls within one of them (172.16/12 prefix). The other options are either public IP addresses that belong to other organizations or networks (11.251.196.241, 171.245.198.241) or invalid IP addresses that do not conform to any standard (193.168.145.241).

If the server is not reachable by name but can be accessed by IP address, it means that there is a problem with name resolution. The hosts file and the DNS server are both responsible for mapping hostnames to IP addresses. Therefore, the server administrator should check these two files for any errors or inconsistencies that might prevent the server from being resolved by name. References:
